Mario Monterosso

The album, titled Take It Away, was initially released on digital formats only on February 14, 2022 by Org Music in Los Angeles. The Memphis Flyer stated that the album’s tracks "offer a guided tour through the instrumental sounds of the '50s and '60s." Both The Sicilian Post and US magazine Exotica Moderne noted that the album expanded on the sound established by guitar duo Santo and Johnny.

In 2022, Tav Falco's Panther Burns undertook an extensive US Tour, which began in August 25 in San Francisco and featured dates in 34 US cities. Monterosso backed Falco on this tour, along with bassist Guiseppe Sangirardi and drummer Walter Brunetti. Monterosso's trio opened for Falco as an instrumental act, playing songs from Monterosso's recent album Take It Away along with other cover songs.

Italian author and attorney Alessandra Tucci wrote the novel Le sei corde dell'anima based on Monterosso's life. The book was published in Italy on April 20, 2021.

In 2020, during the COVID-19 pandemic, Falco began a musical collaboration with Mike Watt at the latter's suggestion. The project developed into a five-song EP entitled Club Car Zodiac, which featured Watt, Toby Dammit, and Argentine surf guitarist Didi Wray amongst others. Monterosso produced, arranged, and played guitar on the album. Club Car Zodiac is released as a purple vinyl 12" 45 rpm EP by ORG Music on Record Store Day Black Friday, November 26, 2021.

In early 2020, Monterosso recorded an instrumental album with Dale Watson that featured all instrumental tracks, four of which Monterosso had written. During this time, he wrote "The Ballad of Zorro," a tribute to the 1975 Italian swashbuckler film Zorro and its Guido & Maurizio De Angelis-penned soundtrack. With this and a number of other songs written, Monterosso then flew to Sicily to visit his ailing mother. While there, he had Rome-based engineer Matteo Spinazzè travel to Sicily to record an album on location in the 18th-century home in Trecastagni owned by his family where he was staying. The album was recorded in summer 2020 with a backup band featuring childhood friends of Monterosso’s. The album was recorded live, and minimal overdubs were added later. One track, "Midnight In Memphis," features narration by Tav Falco. A video for "The Ballad of Zorro" was filmed in Sicily by singer-songwriter Fabio Abate.

On July 8, 2019, Monterosso recorded the single "Steady Girl" b/w "Waiting for a Beer" at Sun Studio in Memphis. The A-side is a cover of an obscure rockabilly song recorded at Memphis Recording Service on December 8, 1956, and was initially unreleased. A collector sold a 78 rpm acetate containing two takes of the track to Black and Wyatt Records, who in turn reissued the tracks as a 7-inch single in 2019. The two tracks were discussed as potentially being the earliest known garage rock recordings. Monterosso’s cover version streamlines the original song, and is coupled with an original song entitled "Waiting For a Beer," the latter recorded in a country & western / honky tonk style. The Monterosso single features layout by Claudio "Greg" Gregori, and was released on January 16, 2020 by Black and Wyatt.

Tav Falco's Panther Burns celebrated its fortieth anniversary in 2019 with a US tour. Dubbed the "40th Anniversary Howl," the tour took place in May and June of that year, with its prime show taking place May 21 in Memphis at Lafayette's Music Room. Monterosso played guitar on this tour. Monterosso performed with Falco and British television and radio personality Jools Holland on BBC Radio 2's The Jools Holland Show on December 15, 2019.

On February 10, 2018, Monterosso, Claudio "Greg" Gregori (Lillo & Greg), Diego "Don Diego" Geraci (The Don Diego Trio), and Italian rockabilly performer Antonio Sorgentone recorded a supergroup project at Sun Studio under the name The Million Euro Quartet. The project was a tribute to the 1956 Million Dollar Quartet session, and featured Gina Haley (daughter of Bill Haley) as guest vocalist.

In April 2018, Falco recorded the sessions that would become the album Cabaret of Daggers at Terminal 2 Studio in Rome, with Monterosso producing and playing guitar once again. Cabaret of Daggers was released by ORG Music on limited edition yellow vinyl on Record Store Day November 23, and on black vinyl and digital formats November 30. Monterosso also played guitar on Tav Falco's Panther Burns' 2018 "Contamination" tour.

In July 2017, Falco entered Sam Phillips Recording Service to record the holiday-themed album A Tav Falco Christmas, with Monterosso producing, arranging, and playing guitar. Watt and Dammit participated in the recording, playing bass and drums respectively. The album was released on vinyl LP in the US by ORG Music on Record Store Day Black Friday, November 24, 2017. The Los Angeles Times called it "gloriously demented enough to act as a tonic for anyone who can't bear the thought of another dose of sugary sentimentality." A track from the album, "Santa Claus is Back in Town," was included on the 2021 digital compilation album XO for the Holidays, Vol. X.

In 2016, Monterosso moved to Memphis, Tennessee, and began working with local artists such as John Paul Keith, Gary Hardy, Brandon Cunning and Jason D. Williams. He produced the album Greetings From Austin for The Don Diego Trio in 2017.

Monterosso toured The United States with Tav’s Falco’s Panther Burns in October–November 2015. Entitled "The Whistle Blower Tour", the tour featured Mike Watt and Toby Dammit, both former members of Iggy and the Stooges, as members of The Panther Burns. Two singles, "Sway" b/w "Where the Rio Dolorosa Flows" and "Me & My Chauffer Blues" b/w "Whistle Blower Blues," were recorded while on the tour. Both singles feature Monterosso on guitar.

In 2014, a friend of Monterosso’s informed him that veteran rock and roll performer Tav Falco was in Rome and was interested in recording there. Monterosso immediately offered his services and was hired. Falco recorded the album in Rome's Exit Studios in August–September 2014. The album, titled Command Performance, was released in 2015 on the UK label Twenty Stone Blatt Records. Monterosso is credited for artistic production and as a member of Tav’s Falco’s Panther Burns, and also co-wrote the album’s songs "Master of Chaos" and "Memphis Ramble" with Falco.

In 2013, Monterosso performed in the theatrical production Chi erano i Jolly Rockers? (Who Were the Jolly Rockers?) alongside Claudio "Greg" Gregori of the theatre duo Lillo & Greg; Lillo & Greg were also featured as part of the production. The production played April 2–21, 2013 at the Teatro Olimpico in Rome.

Sicilian rockabilly musician Vince Mannino was an early mentor to Monterosso and inspired him to began learning guitar, with Chuck Berry, Carl Perkins, Scotty Moore, and Brian Setzer being a few of his early influences. Monterosso began performing live at the age of 14. He moved to Rome to further his career as a musician, while working as a clerk in the Italian court chancellery by day. He performed as sideman to singer Carmen Consoli on an Italian tour in December 2004.

Monterosso recorded an album of semi-autobiographic songs that re-imagined himself as an Italian immigrant to the United States in the 1940s. When cabaret owner Maria Freitas heard the songs, she suggested building the album into something larger. The resulting cabaret production, Fui e Sono Eddie Redmount, debuted in Freitas' La Conventicola Degli Ultramoderni in Rome in November 2017. The production was later directed by Claudio "Greg" Gregori, and played at Catania's Teatro MUST (formerly known as Teatro Angelo Musco) in March 2018, and again at Teatro Manzoni in Rome in December 2019.
