[2][3] From 2006 to 2009, he played in the punk rock band Flipper, and in 2011 he contributed bass and accordion to the song "I Should Have Known" on the Foo Fighters' studio album Wasting Light.

Krist Anthony Novoselic was born in Compton, California, on May 16, 1965, the son of Croatian immigrants Kristo Novaselić and Marija Mustać.

[13][14] The original Croatian surname of Novaselić was mistakenly changed to Novoselic by a clerk when Kristo was applying for a passport to go to America.

[13] Novoselic lived in Compton for one year before his parents moved to the ethnically Croatian Los Angeles neighborhood of San Pedro.

[13] He became interested in punk rock, and discovered bands such as the Sex Pistols and the Ramones when he lived in Croatia at the age of 14 for one year.

[19][20] He has cited Paul McCartney, Geezer Butler, John Entwistle, and Gene Simmons as fundamental influences of his bass playing.

Cobain eventually befriended the older Novoselic, as the pair had similar musical tastes, including a fondness for local band Melvins.

[25] Burckhard lasted only a few months and Melvins' drummer Dale Crover filled in until Novoselic and Cobain met Chad Channing.

[29] Later in 1990, Melvins' singer-guitarist Buzz Osborne encouraged Novoselic and Cobain to check out a punk band called Scream.

Novoselic spent the following months with Nirvana traveling to various labels as the band shopped for a deal, eventually signing with DGC Records.

[45][46][47] Prior to their 1994 European tour, the band scheduled session time at Robert Lang Studios in Seattle to work on demos.

[58] In 1998, Novoselic directed his first movie, L7: The Beauty Process, a pseudo-documentary that utilizes concert footage taped in 1997 in three American cities.

[62][63] In 2002, Novoselic performed uncredited background vocals on Foo Fighters' song "Walking a Line", written as a tribute to Cobain, during the One by One album sessions.

He then joined former Meat Puppets[64] front man Curt Kirkwood and former Sublime drummer Bud Gaugh to form Eyes Adrift.

Following the end of Eyes Adrift, Novoselic announced that he was quitting the music business, noting that he disliked the process of building up publicity for new records.

"[70] In November 2006, it was announced that Novoselic would join Flipper,[71] replacing Bruno DeSmartas on bass, for a tour of the United Kingdom and Ireland.

[76] Novoselic also played bass on children's music artist Caspar Babypants' 2010 album This Is Fun!, for a cover of the Nirvana song "Sliver".

In late July 2017, Giants in the Trees released their first song, "Sasquatch", which features a music video Novoselic joked as "costing over 2 million U.S. dollars to produce".

[93] Novoselic has been currently working with musicians such as Soundgarden's Kim Thayil, alongside Matt Cameron, with production being handled by Jack Endino, as a new band, called 3rd Secret.

A self-titled album was released in April 2022, with eleven songs recorded at The Bait Shop, in Ballard, Washington, as well as Novoselic's home.

[95] During the encore of the Foo Fighters' show on August 29, 1997, at Memorial Stadium as part of the Bumbershoot festival, Novoselic played bass on covers of "Purple Rain" and "Communication Breakdown".

[96] In January 2002, Novoselic performed backing vocals for a non-album Foo Fighters track titled "Walking a Line", later released on a special edition of their album One by One.

[97] During the encore of Foo Fighters' secret show at Paladino's in Tarzana, California on December 22, 2010, the band, with Grohl on drums, was joined onstage by Novoselic and the band's live guitarist Pat Smear for a version of Nirvana's "Marigold", a 1992 Grohl original, which was a B-side on Nirvana's "Heart-Shaped Box".

[98] Novoselic also recorded bass and accordion for the song "I Should Have Known", appearing on Foo Fighters' seventh studio album Wasting Light.

[100] Ten months later, on October 6, 2018, Novoselic joined the band during an encore to play several Nirvana songs, with Grohl on drums, Pat Smear on guitar, and John J. McCauley and Joan Jett filling in as their lead singer.

[107] Over the next several years, JAMPAC fought a number of different issues, including the Teen Dance Ordinance, a 1985 law that strictly limited the ability of minors to attend shows.

[124][125] In June 2020, Novoselic made a Facebook post discussing President Donald Trump's speech in response to unrest following the murder of George Floyd.

[126] After receiving backlash for the original post, Novoselic clarified: "As an avowed independent, I don't endorse a major party or candidate.

To qualify as a political party, he announced a campaign for president in the 2024 United States presidential election, with a goal to gather 1,000 signatures.

[135] In 2014, ahead of Nirvana's induction into the Rock and Roll Hall of Fame, Novoselic and Dave Grohl made guest appearances on The Tonight Show Starring Jimmy Fallon.
