Dan Avidan

In April 2020, Avidan announced an upcoming collaborative album of acoustic covers together with previous NSP collaborators Super Guitar Bros, titled Dan Avidan & Super Guitar Bros; the first single, a cover of Seal's "Kiss from a Rose", was released the same month.

In May 2018, Tupper Ware Remix Party released an album entitled Together Through Time, which featured Avidan on the ninth track, called "Starlight Brigade". A music video was released in May 2019, also featuring animation from Knights of the Light Table. The video was aired on Adult Swim’s late-night anime block Toonami on August 3rd 2019.

The group has released several studio albums and singles, many of the latter of which have charted on Billboard. As of 2019, they have released four studio albums, and three cover albums. On September 17, 2018, the band, along with Tupper Ware Remix Party, performed a censored version of "Danny Don't You Know" on the late-night talk show Conan as a musical guest, making their live television debut.

In September 2017, the band Night Runner released an album entitled Thunderbird, which featured Avidan on the fourth track, called "Magnum Bullets". A music video was released in February 2020, with animation from Knights of the Light Table.

In 2015, Internet personalities Jesse Cox and Michele Morrow began developing an untitled comedy webseries for YouTube Premium, casting Avidan as eSports coach Alex Taylor, alongside Hanson's character, Ryland Smith. After Dan Harmon joined as an executive producer in 2016, the project gained media traction, and was formally announced at VidCon 2017 with the title Good Game. Six serialized episodes were uploaded to the Game Grumps YouTube channel, with the first episode being free-to-view, and concurrent episodes requiring a YouTube Premium subscription. Avidan's performance was well-received by critics, cited as "truly fun, believable," and "[shining] a light on the potential of other projects."

On August 3, 2015, Avidan performed with Steel Panther at their West Hollywood House of Blues venue, singing "Party All Day". The two have collaborated on multiple occasions, with Steel Panther making a cameo in Ninja Sex Party's "Road Trip" music video, and providing vocals for "6969".

In mid-2013, Jon Jafari left his position as co-host of the Let's Play webseries Game Grumps. Arin Hanson, co-creator of Game Grumps, brought Avidan on to replace Jafari as co-host, after being introduced to Ninja Sex Party's content by fellow animator Ross O'Donovan. Hanson had previously animated part of the band's music video for “Dinosaur Laser Fight” in 2011. Avidan's first appearances on the show had been originally met with a negative response from fans, with the number of dislikes on each consecutive video increasing. Avidan would also join O'Donovan as co-host of the Game Grumps spin-off show Steam Train, where both hosts play PC games, as opposed to console games. Avidan remained a co-host of the show until its discontinuation. In addition to this, Avidan has acted as a co-host of other shows from the Game Grumps platform, including Grumpcade, Table Flip, and Steam Rolled, as well as providing narration for Hunting Monsters.

In late 2013, Avidan teamed up with Wecht and Hanson to announce a side project band named Starbomb, with Avidan as the lead singer. The band writes parody songs about video games, bringing together the sexually provocative music stylings of Avidan's Ninja Sex Party and the video game-based humor of Hanson. As of 2019, the group has released three albums, all of which have placed on various Billboard charts.

In 2012, Avidan briefly partnered with Mondo Media to host a sketch comedy miniseries called Dirty Shorts, in which Avidan portrayed an exaggerated version of himself, similar to that of Danny Sexbang. The series was not received well, and was dropped after the first 12-episode season. Avidan has commented that the Mondo Media staff experience was welcoming, although he was not confident that the way his character was written would appeal to audiences. Avidan also co-created, co-wrote, and provided voice acting for the studio's short-lived animated comedy miniseries DJs in PJs with Wecht. Avidan returned to Mondo in September 2013 to compose "Dick Figures: The Movie: The Song" for the Dick Figures: The Movie soundtrack with Wecht.

In 2009, Avidan and producer William J. Sullivan collaborated to compose and sell multiple theme and background tracks for various shows while Avidan studied in New York, with clients ranging from Power Rangers RPM to White Collar.

In 2008, Avidan began studying storytelling and improv at the Upright Citizens Brigade Theatre in New York, under the guidance of Zach Woods and Margot Leitman, and had conceptualized the possibility of a new musical project. In need of another band member, Avidan was introduced to Brian Wecht, the musical director of another troupe, by mutual friends at the theatre in early 2009.

In the winter of 2006, Avidan teamed up with Peter Lennox to form a Brooklyn-based alternative rock duo named Skyhill. Again, Avidan acted as lead singer and lyricist, and the group released one full album, Run With The Hunted, on May 16, 2007. They toured New York in early 2008, before eventually separating due to lost passion. On October 7, 2015, Avidan and Lennox returned to release the single "Firefly", acclaimed for the band's "maturing in both lyrics and sound" over their previous album. Avidan has stated that Skyhill may start new projects in the future, but as of May 2020, nothing has been announced, nor is in the works.

In response to a Craigslist ad in late 2002, Avidan joined the indie rock band the Northern Hues, a Philadelphia-based group composed of Aron Brand, Jeff Rains, Alex Yaker, Justin Earley, and Ian Creech. Avidan acted as the group's lead singer, and provided most of the band's lyrics, having recently moved to Philadelphia. They released one self-titled EP and one live track recorded in early 2005, at World Cafe Live in Philadelphia. In mid-2005, the band split up; Avidan attributes the separation to personality conflicts and creative differences between the band's members, as well as a collective inability to gain greater recognition and success.

After graduating from Jonathan Dayton High School in 1997, Avidan pursued advertising at Boston University in Boston, Massachusetts. He eventually entered a student exchange program during his senior year of college, attending a Tufts University satellite campus in Talloires, France to study botany and epidemiology.
