Flea

On April 26, 2020, Flea will perform during "The Pathway to Paris Earth Day 50: A Virtual Festival", a livestream event to celebrate the 50th anniversary of Earth Day. The festival will stream on the event's Instagram page.

In December 2019, the Red Hot Chili Peppers announced that guitarist John Frusciante would be returning to replace Josh Klinghoffer. The band will focus on making a new album, which they hope to have released in 2020, along with performing a few festival dates.

On 22 October 2019, Flea married 39-year-old designer Melody Ehsani just one month after the couple announced their engagement. Flea said of his second marriage "My life has changed forever and I am eternally humble and grateful. The person who sees all of me and knows who I am. My wife @melodyehsani."

Flea has been very outspoken on the issue of climate change saying in January 2019 "the destructive effects of climate change are ongoing and will be difficult for us human beings to deal with. Love is the only thing that can help us. Love each other, love the earth, let's be there for each other." Days later the Red Hot Chili Peppers performed at a benefit concert for victims of recent deadly Woolsey Fire in California which killed four people and destroyed over 1,500 homes. The fires even halted the recording for the Chili Peppers' twelfth album.

Flea will promote the book by going on a book tour in various places throughout the United States from November to December 2019. He also made an appearance on CBS This Morning on 2 November 2019.

On 16 February 2018, Flea took part in the 2018 NBA All-Star Celebrity Game on a team led by Justin Bieber.

In February 2018, Flea released a passionate and revealing op-ed through Time magazine about the current Opioid crisis as well as his own personal history of drug addiction which for most of his career he had been very private about. Flea hoped that by exposing his past issues with substance abuse that his stories could possibly help others battling their own addictions and raise more awareness on the need for those in the medical community and the government to help those in need. "I've been around substance abuse since the day I was born. All the adults in my life regularly numbed themselves to ease their troubles, and alcohol or drugs were everywhere, always. I started smoking weed when I was eleven, and then proceeded to snort, shoot, pop, smoke, drop and dragon chase my way through my teens and twenties," Flea said. Flea finally kicked his addictions in 1993; however, he revealed that in 2014 when he broke his arm in a snowboard accident he nearly had setbacks due to Oxycontin that his doctor prescribed for him "My doctor put me back together perfectly, and thanks to him I can still play bass with all my heart. But he also gave me two-month supply of Oxycontin. The bottle said to take four each day. I was high as hell when I took those things. It not only quelled my physical pain, but all my emotions as well. I only took one a day, but I was not present for my kids, my creative spirit went into decline and I became depressed. I stopped taking them after a month, but I could have easily gotten another refill. Addiction is a cruel disease, and the medical community, together with the government, should offer help to all of those who need it."

In February 2018, it was announced that Flea's long-awaited memoir, Acid for the Children, would be released on 25 September 2018; however, a few months later the release date was pushed back to 27 November 2018. On 27 September 2018, Flea announced on Twitter that his book has been postponed until 2019 saying "Dear everybody, Due to some scheduling conflicts, the release of my memoir has been delayed until next year. Will have a date as soon as possible. Sorry about any inconveniences.sincerely, flea.

Flea co-stars with Lucas Hedges, Nicole Kidman and Russell Crowe in the 2018 film Boy Erased.

In 2017, Flea played Eddie No-Nose in Edgar Wright's action film Baby Driver. That same year he had a cameo appearance during the fifteenth season of the FOX animated television series Family Guy in an episode titled "Peter's Def Jam". In a scene where Stewie Griffin said to his dog Brian Griffin that thanks to him, there's a recurring flea problem in Stewie's room, Flea enters and drops a bass line on his guitar. He asks Brian if he wants to hang out, but Stewie kicks Flea out of the room.

On 13 April 2016, Flea performed a bass rendition of The Star-Spangled Banner before a game at the Staples Center in Los Angeles between the Los Angeles Lakers and Utah Jazz; this was NBA superstar Kobe Bryant's final game.

In February 2016, the Chili Peppers performed at a "Feel the Bern" fundraiser in support of presidential candidate Bernie Sanders. Flea said, "Bernie Sanders is the only remotely reasonable candidate for President of the United States."

In August 2016, Flea paid a visit to see Koko the gorilla and to also raise awareness for The Gorilla Foundation. The foundation said of Flea's visit "One of Koko's favorite musicians, Flea from the Red Hot Chili Peppers came to visit. Koko was thrilled by the mellow sounds and a jamming session followed with Koko strumming on Flea's bass!"

From "The Getaway" world tour beginning June 2016. Flea was back on the road with three Custom Shop Fender Jazz basses.

In February 2015, Flea posted photos to his Instagram page showing that he had broken his arm during a skiing trip. His injury delayed the recording of the Chili Peppers eleventh studio album for six months with production expected to resume in mid-August according to Flea, who said on 3 August, he was now healed enough to play bass again and continue recording.

In May 2015, Flea reached out to fans to help donate to the Special Olympics. Two lucky fans will be selected to be flown out to meet Flea for private bass lessons.

In August 2015, Flea added an apiary in his backyard which includes three beehives with approximately 60,000 bees each and over 200,000 bees total in his backyard in efforts to restore the honeybee population. Flea commented on his new obsession with beekeeping by saying "Deep to the hive super organism. I love my bees. Flea's bees."

On 18 September 2015, Flea and his Chili Peppers bandmates were among over 120 entertainers and celebrities to announce that they would be voting for Bernie Sanders in the 2016 election for President of the United States.

The event, which cost $2,500 and was limited to 300 tickets also included dinner and a silent auction. The Chili Peppers performed a rare acoustic set and John Legend headlined the event.

Flea took part in the Pathway to Paris concert in December 2015. The all-star event aimed to raise awareness about the urgency of climate action and coincided with the UN Climate Change Conference in Paris.

In 2015, Flea appeared as himself in the Amazon Prime series, Highston. It was announced in 2017 that Amazon Prime had cancelled plans for a full series of the show.

When we [the band] made Blood Sugar Sex Magik we spent a lot of time jamming—every day, for hours and hours. I remember during that time Anthony went off and made a movie, and for a long time it was just me, John and Chad, and we'd just go in there and play. Me and John were hitting the bong and we just rocked and grooved forever. It was the first time we went in to make a record where there wasn't this feeling of being sort of intimidated by what was going to happen.

It was announced on 1 April 2014 that Flea was in the process of writing his own personal memoir which will be released through Grand Central Publishing. No release date has been set or a title for the book which according to the press release will detail Flea's younger years as a rebellious teenager on the streets of L.A. where he befriends fellow high school classmate, Anthony Kiedis, Hillel Slovak and Jack Irons and forms the Red Hot Chili Peppers. The book will detail his long and sometimes complex friendship and collaboration with Kiedis, his drug usage and the tumultuous creative journey of the band.

On 9 April 2014, it was revealed that Flea was working on a new musical project titled Antemasque, with former Mars Volta members Cedric Bixler-Zavala, Omar Rodríguez-López, and Dave Elitch. Two songs were released in early April though Flea has confirmed that he is not a member of the band and just recorded a few songs with them. Antemasque released their self-titled debut album on 15 July 2014.

Flea made his return to acting and co-starred in the 2014 film, Low Down, which is based on the life of jazz pianist, Joe Albany. Flea along with Anthony Kiedis executive-produced the film which stars John Hawkes, Elle Fanning, Glenn Close, and Peter Dinklage. The film had a successful debut at the Sundance Film Festival in January 2014 and opened in limited release in October 2014. It was released in March 2015 on DVD.

On 19 August 2014, Flea posted took part in the Ice Bucket Challenge.

In April 2014, Flea started writing his own book, his memoirs. The book will chronicle Flea's unconventional childhood (including his move from a "normal" life in the New York suburbs to a "bohemian" lifestyle in Los Angeles with his jazz-playing stepfather), his adventures in the L.A. streets, his "sometimes complex friendship and collaboration" with Chili Peppers co-founder Anthony Kiedis and the overall "tumultuous creative journey" of the band, which formed in 1983.

"Damien actually made me a bass, a butterfly bass, it's a beautiful thing. "It's not just a piece of art to hang on a wall. The whole new album I play on it. This bass is kind of heavy for live—I don't play Fenders that much live—but it's beautiful".

The 2014 film Low Down, also starring Lena Headey, Peter Dinklage, Elle Fanning, and Glenn Close, marked Flea's first acting role in 14 years. The film was directed by Jeff Preiss, who previously worked with Flea on the 1988 documentary Let's Get Lost. In 2015, he provided the voice of the "mind cop" Jake in the Pixar film Inside Out.

On 11 May 2013, the Chili Peppers performed a special concert in Portland, Oregon for the Dalai Lama as part of the Dalai Lama Environmental Summit. According to the press release, "The musical element of this event is intended to be a display of joyful celebration and an inspiration to future generations to care for our planet. The Red Hot Chili Peppers have been great supporters of the Tibetan cause, of His Holiness the Dalai Lama, and of the need to work to protect and preserve our environment."

Flea has been very outspoken towards guns and gun violence, sometimes speaking about it during Chili Peppers shows. He often expresses his anger on his Twitter page. In 2013, he said "why anyone would ever want to own an automatic weapon I will never ever understand. it's a pathetic useless concept for sick people. Automatic, semi automatic, I don't care. I'm against em........ Melt em all down turn em into sculptures there is no need for them on earth. In many countries, the cops have no guns and they do perfectly fine. No civilians should be allowed to have guns. none. and I don't think the cops should have guns either. change the constitution". Following the racially motivated Charleston church shooting in June 2015, Flea again voiced his anger towards gun violence saying "You are kidding me. This is too much. Humans are an over rated species. Sick. God help us." and "The USA land where any sick madman can easily get a gun. disgusting, deplorable, unbelievable."

The debut album by Rocketjuice and the Moon was released on 12 March 2012.

On 19 July 2012, Flea released a solo EP, Helen Burns, composed mainly of instrumental tracks, except the title track (which Patti Smith sang on) and "Lovelovelove", which features the Silverlake Conservatory of Music's kids and adults choir. It is Flea's first solo release, who has only released solo songs previously on soundtracks and other projects. Flea said of the EP "I am putting it out to raise money for the Silverlake Conservatory of Music, a community based non-profit music school that I am an integral part of." The download of the EP is available at "a name your own price" on the Silverlake Conservatory website and was made available through all major digital outlets on the 9th August 2012.

On 16 October 2012, his 50th birthday, Flea gave an interview with CNN discussing the Chili Peppers and was asked if he plans to continue with them. Flea responded by saying "I love the Chili Peppers, and I would love to. If there's anything I know, it's every time you start making plans, you don't know what's going to come up next. Anything can happen. So I love being in the Chili Peppers and it's my home, and I've been doing it for more than half my life. Of course, during the course of doing it, there's been all kinds of ups and downs, and moments of extreme (positivity), floating on clouds of greatness, and times of just groveling, and misery, and uncertainty, and anger, and love and all those things. Like being in a family. I really can't predict. But I love being in it for now, and right now, about as far as I'm thinking is getting through this tour that we're doing, performing at the highest level possible, then hunkering down and writing another record."

The Chili Peppers performed a free concert in downtown Cleveland, Ohio on 15 April 2012, in support of President Barack Obama's re-election campaign.

In June 2011, Flea announced that he was giving away a personally customized bass guitar covered with graffiti and a one-on-one bass lesson as a prize in an eBay auction. The auction will benefit Style Wars, a 1983 documentary on early hip hop. The auction will raise money for restoring the film's negatives. Brad Pitt, James Franco, and Spike Jonze also took part in the auction, which ended on 11 June 2011.

In a 23 June 2011 interview, Flea discussed the band's return and how he almost quit the Chili Peppers during their hiatus. Flea said, that he just felt like he wanted to take two years away just to really look and see if the band was "something we should still be doing". "Things had gotten dysfunctional and not fun, even though I thought we were making great records, doing great shows and were a really powerful, mighty thing as a band. I was proud of what we did." "For me, the biggest thing during the time off, and what really made me want to continue doing the band, specifically after decided he didn't want to continue in the band anymore, [was] I just realized, Anthony, man, he's my brother, I love him so much, and we started this band when we were kids. I wanted to keep that going, I never want to let that go. Playing with him is something, even though I can do other things that are exciting and beautiful and I always will do those things and I'll always want to grow and do music outside of the band, the thing that we have is special to us and something that is blood."

The Red Hot Chili Peppers released their tenth studio album, I'm with You on 29 August 2011.

Flea played bass on two songs on Tom Waits's 2011 album Bad as Me, released on 21 October.

On 27 October 2011, it was announced that Flea's side-project with Damon Albarn and afrobeat legend, Tony Allen would be called Rocket Juice & the Moon. According to Albarn, on where the band's name came from, someone in Lagos did the sleeve design and that's the name he gave it, which he said he is fine with, because trying to find a name for another band is always tricky. The band made their live debut on 29 October 2011, in London and their debut album was released in 2012.

On 7 December 2011, the Red Hot Chili Peppers were announced as 2012 inductees into the Rock and Roll Hall of Fame. Flea commented on the induction by saying, "It's always been easy for me to pooh-pooh these awards—the [Rock] Hall of Fame too. But I inducted Metallica a couple of years ago, and it was really a beautiful thing to see as all these people were being inducted. It made me love it. I love halls of fame anyway—the Basketball Hall of Fame, the Baseball Hall of Fame. So I feel grateful for the recognition of what we have done and for the hope and potential of what we'll continue to do."

Flea appeared in the 2011 documentary The Other F Word, where he discussed the joys of being a father by saying "It's funny how you always hear people saying that classic parent attitude of, 'I brought you into this world, I gave you life!' You know, it's just, I think, completely the opposite. My kids gave me life. They gave me a reason."

On 20 March 2011, Flea ran the LA Marathon to raise money for the Silverlake Conservatory of Music through Crowdrise. Flea was also featured in Runner's World magazine discussing his preparation for the race.

In April 2011, Flea finished second in an online poll conducted by Contact Music to name the best bass guitarist in rock music. Flea lost to the late John Entwistle of the Who. Rounding out the top five were Paul McCartney (the Beatles), Geddy Lee (Rush) and Les Claypool (Primus).

In 2011, Flea appeared in the documentary, Bob and the Monster. The film details the life of musician and drug counselor Bob Forrest.

Flea incorporates elements of funk (including slap bass), psychedelic, punk, and hard rock in his style of playing. In 2009, Rolling Stone readers ranked Flea the second best bassist of all time, behind only John Entwistle. In 2012, he and the other members of Red Hot Chili Peppers were inducted into the Rock and Roll Hall of Fame.

In 2009, Flea joined Atoms for Peace, a supergroup formed by Radiohead singer Thom Yorke to perform songs from Yorke's debut solo album, The Eraser (2006). The band toured the United States in 2010, and released an album, Amok, in 2013. The album was followed that year by a tour of Europe, the US, and Japan.

The Chili Peppers ended their hiatus in October 2009 without Frusciante, who quit the band to pursue other musical interests. He was replaced by Josh Klinghoffer. The band began rehearsing and writing for their tenth studio album.

In 2009, Flea founded the Fleabass company with the goal to create quality budget basses for beginners. Whilst Flea did not perform with his own Fleabass production model he did however use a custom model created by UK artist Damien Hirst.

Regarded as one of the best rock bass players of all time, in 2009, Rolling Stone' s readers ranked Flea the second-best bassist of all time in their top-ten poll, ranked behind only John Entwistle and ahead of Paul McCartney. In a 2010 poll, conducted on the BBC Two series I'm in a Rock 'n' Roll Band!, Flea was named the bassist in the ultimate fantasy band alongside Freddie Mercury on vocals, Jimi Hendrix on guitar and John Bonham on drums.

After the Chili Peppers announced a long hiatus due to exhaustion, Flea enrolled in music classes at the University of Southern California. Beginning in the fall of 2008, he studied music theory, composition and jazz trumpet. Flea attributed his interest in attending such courses to a newfound desire to widen his appreciation and understanding of music: "it's so much fun to learn this stuff because I never knew anything. I played trumpet in the school bands. I learned things I liked to play on my trumpet but I didn't learn why this note goes with this note and why it produces that sound. Or how to create tension in the composition [...] Knowing the structure is really fun." Flea also revealed plans to release a mainly instrumental solo record, recorded in his home; guest musicians include Patti Smith and a choir from the Silverlake Conservatory.

In October 2008, Flea (along with his daughter Sunny Bebop) appeared in a Vote for Change ad voicing his support for Barack Obama for president of the United States in the upcoming election.

After another two-year world tour, the Chili Peppers wrote their ninth studio album Stadium Arcadium (2006). Unlike By the Way, both Flea and Frusciante were more musically conjoined, when writing the record. They found inspiration in Jimi Hendrix, Jimmy Page, and Eddie Van Halen among others. The double album was ultimately released on 9 May 2006, to generally positive reviews, selling over seven million copies in less than two years. In November 2007, Flea's $4.8 million Corral Canyon home in Malibu was burnt down by a wildfire. The location was not, however, his primary residence and at the time of its destruction was being rented to musician and producer Butch Walker.

Flea was engaged in 2005 but never married model Frankie Rayder who was once named GQ magazine's sexiest woman in the world. They had a child together, Sunny Bebop Balzary, who was born on 26 October 2005. The song "Hard to Concentrate" on the Chili Peppers' 2006 album, Stadium Arcadium, was written by Kiedis as a wedding proposal to Flea and Rayder. Flea and Rayder have since split up.

In September 2005, the Chili Peppers performed "Under the Bridge" at the ReAct Now: Music & Relief benefit which was held to raise money for victims of Hurricane Katrina. Thirty million dollars was raised during the live event which was broadcast across the world on various television networks and online.

Red Hot Chili Peppers spent most of 2001 writing their eighth studio album, By the Way (2002). The band began listening to more melodic, textured music, that would reflect heavily on the album. Frusciante became the driving force behind By the Way, causing initial strife between him and Flea. If he introduced a funk rhythm into his bass lines Frusciante would consequently disapprove to the point where Flea almost quit the band because he felt his role was no longer important. By the Way was released on 9 July 2002 to positive reviews. By the Way would go on to sell over nine million copies worldwide. The ensuing tour was extremely profitable; the Chili Peppers performed three concerts in London's Hyde Park to over 250,000 attendees and a total gross accumulation of US$17.1 million. It became the highest-grossing concert at a single venue in history.

In By the Way (2002), many of the bass-lines were entirely stripped of funk. Flea felt the chords Frusciante had written were not supportive of his typical technique; furthermore, he does not feel the musical direction of the record was specifically melodic, but instead "... a result of each one of us being who we are. The way we [the band] compose music is a very communal thing."

Flea is also the co-founder of Silverlake Conservatory of Music, a non-profit music education organization founded in 2001 for underprivileged children. In 2019 his memoir Acid for the Children was published, detailing his life prior to the formation of Red Hot Chili Peppers.

In 2001, he co-founded the Silverlake Conservatory of Music with his childhood friend Tree. The school is dedicated to help youth progress in music. "I just wanted to fill the void that public education has cut from their curriculum. They've dropped the ball by cutting out music programs", Flea laments, "I grew up in LA public schools and was in the music department. It was really an important thing for my life, it gave me something to hold onto, and it was an important access for me. Without music I would've gotten into a lot of trouble and there are a lot of kids like me out there. I just wanted to try to provide something like what I got." Flea felt the public school system was seriously lacking in exposing children to music by drastically reducing, and sometimes eliminating, art-related programs.

Flea was heavily influenced by electronica during the writing and recording of Californication (1999) and he attempted to emulate this when writing bass lines for the album. Californication took less than two weeks to record; by contrast, One Hot Minute took over a year. When Californication was released on 8 June 1999 it received overwhelmingly positive critical reviews and sold fifteen million copies worldwide—more than Blood Sugar Sex Magik. The Chili Peppers played Woodstock 1999, with Flea playing completely naked—something he would do again at the Reading and Leeds Festivals the same year as well as several other Californication tour concerts.

Flea became interested in electronica during the Californication (1999) era and he attempted to emulate the same atmosphere given off by synthesizers into his bass playing: "I feel the most exciting music happening is electronica, without a doubt." He ultimately decided against this, acknowledging that, aside from Frusciante, the band was not moving in the same direction.

The band, with Frusciante back on guitar, began writing new songs during the summer of 1998 in Flea's garage. He and Kiedis were less confident in writing the album after the disappointing results of One Hot Minute. Flea had also recently broken up with his girlfriend of two years, Marissa Pouw, causing him to enter a state of depression which was only lifted when his daughter, Clara, comforted him after several weeks of crying.

The Chili Peppers were invited by the Beastie Boys and the Milarepa Fund to perform at the Tibetan Freedom Concert in June 1996 in San Francisco. They also performed at the June 1998 Washington, D.C. concert as well. The concerts, which were held worldwide, were to support the cause of Tibetan independence.

Following the tour in 1993, Flea was diagnosed with chronic fatigue syndrome and was ordered to rest for a year. Flea and Kiedis felt it best to fire Marshall due to lack of chemistry and briefly replaced him with Jesse Tobias, although his tenure was very short and he was quickly replaced by Jane's Addiction guitarist Dave Navarro, who was once recruited in 1992 to replace Frusciante. The band was ready now to record their next album although Kiedis was in the middle of a heroin relapse, which forced Flea to assume the role of lyricist, something he had not yet done. He wrote most of the song "Transcending", and the intro to "Deep Kick". Flea also wrote the entire lyric to a song, "Pea", in which he both played bass and sang. These three songs appeared on the Chili Peppers' sixth record One Hot Minute, which was released on 12 September 1995. The album received mixed reviews and was significantly less commercially successful than Blood Sugar Sex Magik. The One Hot Minute Tour was ultimately cut short due to various injuries Kiedis and Smith received, and the Red Hot Chili Peppers decided to go on hiatus. Flea was so miserable that at one point during the tour he discussed quitting the band. Flea began to practice Transcendental Meditation and yoga, and slowly decreased his marijuana consumption. Due to the Chili Peppers' inactivity, Flea joined Navarro in a Jane's Addiction reunion tour in 1997, filling in for ex-Jane's Addiction bassist Eric Avery. Rumors spread, that the band was breaking up until Navarro stated otherwise: "I want to clarify that the Chili Peppers are not breaking up ... Flea and I are more than happy to do both projects, time permitting."

Flea also had plans to record a solo album. He asked Chili Peppers manager Lindy Goetz to help him promote the record and his future solo career. Flea eventually abandoned the idea in favor of offering his bass services to other artists. He performed on over forty records from 1995 to 1998, ranging from Alanis Morissette's Jagged Little Pill to former Minutemen bassist Mike Watt's debut solo album Ball-Hog or Tugboat?. He also worked with Tori Amos and Michael Stipe on a track for the soundtrack to the 1995 Johnny Depp film Don Juan DeMarco. Navarro was fired from the Chili Peppers in 1998, and Flea questioned whether or not the Red Hot Chili Peppers would stay together: "... the only way I could imagine carrying on is if we got John [Frusciante] back in the band." Frusciante had completed drug rehabilitation in 1997 after a severe addiction to heroin and crack cocaine left him on the brink of death. Flea visited Frusciante in early 1998, inviting him back to the Chili Peppers; an emotional Frusciante readily accepted.

During the writing and recording of One Hot Minute (1995), Flea integrated some use of slap-bass progressions, but continued to center his technique around the philosophy of "less is more" rather than complexity: "I can't even think of anything I played that was complex [on the record]; even the slapping stuff is simple. It's original-sounding, and I'm proud of that—but what I played was more a matter of aesthetic choice." This led Flea to alter the way he wrote music by playing alone, instead of the jam sessions that would dictate how the band conceived songs: "[One Hot Minute] is the least jam-oriented record we've made. I mean, we definitely jammed on the ideas, but there's only one groove on the whole album that came from a jam, 'Deep Kick'. The rest of it came from my sitting down with a guitar or bass."

Flea has also appeared in television broadcasts with Red Hot Chili Peppers on several occasions. Several months before Frusciante's departure in 1992, the band performed two songs on Saturday Night Live—Kiedis felt the show was an embarrassment due to the guitarist; he believed, that Frusciante purposely played the song out of tune and incorrectly. Later that year, the band appeared in the popular animated comedy The Simpsons on the episode "Krusty Gets Kancelled". At Woodstock 1994, Kiedis proposed the band perform the first few songs in metallic suits with giant light bulbs placed on their heads. Flea was initially reluctant but eventually agreed: "... when we got to play, the energy of the whole thing took over."

When Blood Sugar Sex Magik was released on 24 September 1991, it received an overwhelmingly positive critical response. The album peaked at number three on the Billboard Hot 200, and went on to sell over seven million copies in the U.S. alone. The album's ensuing tour was critically acclaimed—the Chili Peppers commonly performed shows with over twenty thousand in attendance. Seattle-based grunge band Nirvana also toured with them during the West Coast leg of their United States tour. The massive attention the Chili Peppers started receiving, however, caused Frusciante to feel extremely uncomfortable, and he abruptly quit the band during the Japanese leg of the album's tour.

Flea played a minor role in the 1991 independent film My Own Private Idaho as the character Budd. He played a number of minor roles in films throughout the 1990s, including Son in Law (1993) as a tattoo artist, The Chase (1994) as a monster truck driver alongside Kiedis, Fear and Loathing in Las Vegas (1998) as a "Hippie", in The Big Lebowski (1998) as a German nihilist, and the 1998 remake of Psycho. He has also lent his voice to the animated series The Wild Thornberrys as the character Donnie.

In 1991, the Red Hot Chili Peppers released a black and white film documenting the recording of Blood Sugar Sex Magik titled Funky Monks. They have released two video concerts, Off the Map in 2001 and Live at Slane Castle in 2003—the latter of which had over eighty thousand attendees.

The ensuing Mother's Milk Tour put even further strain on Flea's marriage. In order to make money, he needed to tour, and therefore spent time away from his family. Furthermore, he and Smith were arrested on charges of battery and sexual harassment after a performance on MTV's coverage of spring break; charges were eventually dropped. The band was, however, attracting over three thousand people per show; Mother's Milk had been certified as a gold record in early 1990. By the time Red Hot Chili Peppers returned to Los Angeles, Flea and Loesha agreed to a separation. He tried to put the separation out of his mind by smoking marijuana and having sex with random groupies, when the band was on tour for Mother's Milk.

In 1990, Flea and Chili Peppers drummer Chad Smith were charged with battery, disorderly conduct and solicitation to commit an unnatural and lascivious act after the two jumped off the stage and assaulted a woman in the crowd. Flea picked up the woman and began to spin her around on his shoulders, while Smith pulled her bathing suit to one side and began to slap her bottom. Officials said Balzary got on top of the woman, asked her to perform a sex act, then began to simulate the act. After the woman cried for help, the band was escorted away. The woman apparently was picked from the audience at random and has signed a complaint against the band members.

Flea and the Chili Peppers appeared in 1990 PSA ads for Rock the Vote, a non-profit organization created to encourage 18- to 24-year-olds in the United States to vote in the upcoming presidential election.

Flea and his wife Loesha started to grow apart, and he began trying to recreate the memories of his adolescence by smoking marijuana on a daily basis. The Chili Peppers entered the studio, and completed recording of their fourth album, Mother's Milk, in early 1989. Upon release, the album was met with mixed reactions from critics, but received far more commercial attention, peaking at number fifty-two on the Billboard 200. After this, Flea made appearances playing the trumpet on Jane's Addiction's 1988 album Nothing's Shocking, and bass on the critically acclaimed 1989 Young MC album Stone Cold Rhymin'. He would also appear in the video for "Bust a Move", the hit single from the same album.

Flea's bass playing has changed considerably throughout the years. When he joined Fear, his technique centered largely on punk rock bass lines; however, he was to change this style when the Red Hot Chili Peppers formed. He began to incorporate a "slap" bass style that drew influence largely from Bootsy Collins. However, this technique caused Flea to receive attention from the music world and was often copied, and he, therefore, felt it necessary to almost completely remove slap-bass styles from his repertoire following Mother's Milk (1989). Consequently, Blood Sugar Sex Magik (1991) saw a notable shift in style as it featured less of his signature technique and more styles that focused on traditional and melodic roots. His intellectual beliefs on how to play the instrument were also altered: "I was trying to play simply on Blood Sugar Sex Magik because I had been playing too much prior to that, so I thought, 'I've really got to chill out and play half as many notes'. When you play less, it's more exciting—there's more room for everything. If I do play something busy, it stands out, instead of the bass being a constant onslaught of notes. Space is good."

Kiedis was briefly kicked out of the band, and given a month to rehabilitate. Kiedis completed the rehab and rejoined the Red Hot Chili Peppers in Los Angeles to record their third album The Uplift Mofo Party Plan (1987). Flea has referred to the album as "the 'rockingest' record" the band has ever made. The Uplift Mofo Party Plan proved to be far more successful, commercially and critically, than the Chili Peppers' preceding albums, registering at number 148 on the Billboard 200. Following the Uplift tour, Slovak's drug use dramatically increased. Flea's relationship with Slovak faded, and Slovak became isolated and depressed. On 28 June 1988, Slovak was found dead of a heroin overdose. Flea reflected: "I didn't really know how to deal with that sadness, and I don't think [Kiedis] knew how to deal with it either." Irons, who was taking Slovak's death particularly hard, left the group.

From 1988 to 1990, Flea was married to Loesha Zeviar (Loesha's name still remains tattooed on Flea's chest). Together they had one daughter, Clara Balzary, who was born in 1988. Clara has been featured in many Chili Peppers books and documentaries including the band's Funky Monks documentary. She also has appeared at many shows and as a child even provided artwork for the band's T-shirts and promotional material. She has also documented the band's I'm With You tour through photographs and videos. As an adult, Clara was most recently in the short-lived band the Tints and is also an aspiring artist and photographer, taking the promotional photographs for the new Red Hot Chili Peppers record.

Funk musician George Clinton was hired to produce the band's second album, Freaky Styley (1985). The strong chemistry between Clinton and the Chili Peppers was felt instantly. Flea later referred to Clinton as "the warmest, kindest man in the world". Freaky Styley was released in August 1985. It received only a bit more attention than The Red Hot Chili Peppers with roughly 75,000 copies sold by year's end. Flea was somewhat indifferent to the poor album sales as he had recently proposed to girlfriend Loesha Zeviar, who was pregnant with their child. The band hired Michael Beinhorn, their last resort among potential producers, to work on their next album. What Is This? had finally disbanded, and drummer Irons returned to the Chili Peppers in mid-1986 after Martinez was fired. Flea, Slovak and Kiedis especially were involved in heavy drug use and their relationships became strained. Flea recalled that "it began to seem ugly to me and not fun; our communication was not healthy". Kiedis became dependent on heroin, leaving Flea and Slovak to work on much of the album's material by themselves.

Since 1984, Flea has acted in over 20 films and television series such as Suburbia, Back to the Future Part II and Part III, My Own Private Idaho, The Chase, Fear and Loathing in Las Vegas, Dudes, Son in Law, The Big Lebowski, Low Down, Baby Driver and Boy Erased, in addition to voicing the character Donnie Thornberry in The Wild Thornberrys animated television series and films.

The band's concert repertoire grew to nine songs as a result of months of playing at local nightclubs and bars. The Red Hot Chili Peppers entered Bijou Studios to record a demo tape produced by the then-drummer of Fear and subsequently secured a record deal with EMI. Irons and Slovak, however, decided to leave the Red Hot Chili Peppers in order to pursue a "more serious" future with rock band What Is This?. Flea ultimately respected the decision, but felt the band would be lost without them. He and Kiedis hired drummer Cliff Martinez and guitarist Jack Sherman to fill Irons's and Slovak's places, respectively. Andy Gill, formerly of Gang of Four, agreed to produce their first album. Gill and Sherman clashed with Flea and Kiedis; they continuously argued over music style, sound, and the album's production. Flea himself felt that the album was stiff and "a big mistake", but also admitted "we [he and Kiedis] were just disrespectful and obnoxious". The band's eponymous debut album, The Red Hot Chili Peppers, was released on 10 August 1984 to largely poor critical and commercial review. After a relatively unfruitful tour, Sherman was fired in early 1985. Slovak, who had been contemplating a return to the Chili Peppers, rejoined the group after being encouraged by Flea.

Flea has displayed a wide variety of techniques throughout the years, ranging from his initial use of slapping and popping to the more traditional methods he has employed since Blood Sugar Sex Magik. Greg Prato of Allmusic wrote that "by combining funk-style bass with psychedelic, punk, and hard rock, Flea created an original playing style that has been copied numerous times". Flea stated in an interview, that he was influenced greatly by Louis Armstrong. Flea has been considered one of the greatest bassists of all time, with Greg Tate of Rolling Stone saying "if there were a Most Valuable Bass Player award given out in rock, Flea could have laid claim to that bitch ten years running". Smashing Pumpkins front man Billy Corgan recalls, that when he first saw the Chili Peppers in 1984, "Flea was playing so aggressively that he had worn a hole in his thumb and he was literally screaming in pain in-between songs because it hurt so bad. Someone kept coming out and pouring crazy glue into the hole." Flea's sound is also determined by what type of instrument he plays. Before Californication, he did not believe the actual bass held much significance: "what mattered was how you hit them [basses] and your emotional intent, and I still think that's the bottom line." Flea owns a 1961 Fender Jazz Bass, treasuring it for its "old wood sound".

Flea has pursued a minor acting career since the mid-1980s. His first role was as young punk Razzle in the Penelope Spheeris film Suburbia (1984). Shortly thereafter he starred alongside the Chili Peppers, who played themselves, in the skate drama Thrashin' (1986). He played the ill-fated punker Milo in another Penelope Spheeris film, Dudes (1987). He also made an appearance in the Bruce Weber documentary film about the life and career of jazz trumpeter Chet Baker entitled Let's Get Lost (1988). He portrayed the character Douglas J. Needles in Back to the Future Part II (1989) and Back to the Future Part III (1990), though in an interview he referred to Part II as "a multi-million-dollar piece of trash", saying that he was happy neither with the film nor his performance in it.

Michael Peter Balzary (born 16 October 1962), known professionally as Flea, is an Australian-American musician and actor. He is best known as a founding member and the bassist of the rock band Red Hot Chili Peppers and has appeared on every album released by the band. Flea briefly appeared as the bassist for such bands as What Is This?, Fear, and Jane's Addiction. He has performed with rock supergroups Atoms for Peace, Antemasque, Pigface, and Rocket Juice & the Moon, and collaborated with the Mars Volta, Johnny Cash, Tom Waits, Alanis Morissette, and Young MC. Flea also performed live with Nirvana in 1993 playing the trumpet.

Michael Peter Balzary was born on 16 October 1962 in Melbourne, Victoria. He is of Hungarian and Irish descent. His father, Mick Balzary, an avid fisherman, often took him fishing. When Flea was four, his family moved to Rye, New York for his father's career. In 1971, his parents divorced and his father returned to Australia. Flea then returned to Australia to spend time with his father, completing three years of school in the national capital Canberra. Flea and his sister Karyn stayed with their mother Patricia, who soon remarried to a jazz musician, Walter Urban (1941–2011). Decades later, Flea would receive American citizenship. He was first called "Flea" as a teenager for his seeming inability to sit still, and the nickname stuck.

Currently, his main stage bass is a Custom Shop Fender Jazz Bass, modified with a Modulus Lane Poor pickup. Fender has released this bass for sale as the Flea Signature Active Jazz Bass, in addition to a signature instrument modelled after his 1961 Fender Jazz Bass.
