Answer by taking a quote from the following article:

Eric Boucher was born in Boulder, Colorado, the son of Virginia (nee Parker), a librarian, and Stanley Wayne Boucher, a psychiatric social worker and poet. He had a sister, Julie J. Boucher, the Associate Director of the Library Research Service at the Colorado State Library (who died in a mountain-climbing accident on October 12, 1996). As a child, Eric developed an interest in international politics that was encouraged by his parents. An avid news watcher, one of his earliest memories was of the John F. Kennedy assassination.

In April 1986, police officers raided his house in response to complaints by the Parents Music Resource Center (PMRC). In June 1986, L.A. deputy city attorney Michael Guarino, working under City Attorney James Hahn, brought Biafra to trial in Los Angeles for distributing "harmful material to minors" in the Dead Kennedys album Frankenchrist. However, the dispute was about neither the music nor the lyrics from the album, but rather the print of the H. R. Giger poster Landscape XX (Penis Landscape) included with the album. Biafra believes the trial was politically motivated; it was often reported that the PMRC took Biafra to court as a cost-effective way of sending a message out to other musicians with content considered offensive in their music.  Music author Reebee Garofalo argued that Biafra and Alternative Tentacles may have been targeted because the label was a "small, self-managed and self-supported company that could ill afford a protracted legal battle." Facing the possible sentence of a year in jail and a $2,000 fine, Biafra, Dirk Dirksen, and Suzanne Stefanac founded the No More Censorship Defense Fund, a benefit featuring several punk rock bands, to help pay for his legal fees, which neither he nor his record label could afford. The jury deadlocked 5 to 7 in favor of acquittal, prompting a mistrial; despite a motion to re-try the case, the judge ordered all charges dropped. The Dead Kennedys disbanded during the trial, in December 1986, due to the mounting legal costs; in the wake of their disbandment, Biafra made a career of his spoken word performances.  Biafra has a cameo role in the 1988 film Tapeheads. He plays an FBI agent who arrests the two protagonists (played by Tim Robbins and John Cusack). While arresting them his character asks "Remember what we did to Jello Biafra?" lampooning the obscenity prosecution.  On March 25, 2005, Biafra appeared on the U.S. radio program This American Life, "Episode 285: Know Your Enemy", which featured a phone call between Jello Biafra and Michael Guarino, the prosecutor in the Frankenchrist trial.  In October 1998, three former members of the Dead Kennedys sued Biafra for nonpayment of royalties. The other members of Dead Kennedys alleged that after Biafra, in his capacity as the head of Alternative Tentacles records, discovered an accounting error amounting to some $75,000 in unpaid royalties over almost a decade. Rather than informing his bandmates of this mistake, the suit alleged, Biafra knowingly concealed the information until a whistleblower employee at the record label notified the band.  According to Biafra, the suit resulted from his refusal to allow one of the band's most well-known singles, "Holiday in Cambodia", to be used in a commercial for Levi's Dockers; Biafra opposes Levi's because of his claim that they use unfair business practices and sweatshop labor. Biafra maintained that he had never denied them royalties, and that he himself had not even received royalties for re-releases of their albums or "posthumous" live albums which had been licensed to other labels by the Decay Music partnership. Decay Music denied this charge and have posted what they say are his cashed royalty checks, written to his legal name of Eric Boucher. Biafra also complained about the songwriting credits in new reissues and archival live albums of songs, alleging that he was the sole composer of songs that were wrongly credited to the entire band.  In May 2000, a jury found Biafra and Alternative Tentacles "guilty of malice, oppression and fraud" by not promptly informing his former bandmates of the accounting error and instead withholding the information during subsequent discussions and contractual negotiations. Biafra was ordered to pay $200,000, including $20,000 in punitive damages. After an appeal by Biafra's lawyers, in June 2003, the California Court of Appeal unanimously upheld all the conditions of the 2000 verdict against Biafra and Alternative Tentacles. Furthermore, the plaintiffs were awarded the rights to most of Dead Kennedys recorded works -- which accounted for about half the sales for Alternative Tentacles. Now in control of the Dead Kennedys name, Biafra's former bandmates went on tour with a new lead vocalist.  In the early 1980s, Biafra collaborated with musicians Christian Lunch and Adrian Borland (of The Sound) for the electropunk musical project The Witch Trials, releasing one self-titled EP in its lifetime.  In 1988, Biafra, with Al Jourgensen and Paul Barker of the band Ministry, and Jeff Ward, formed Lard. The band became yet another side project for Ministry, with Biafra providing vocals and lyrics. According to a March 2009 interview with Jourgensen, he and Biafra are working on a new Lard album, which is being recorded in Jourgensen's El Paso studio. While working on the film Terminal City Ricochet in 1989, Biafra did a song for the film's soundtrack with D.O.A.. As a result, Biafra worked with D.O.A. on the album Last Scream of the Missing Neighbors. Biafra also worked with Nomeansno on the soundtrack, which led to their collaboration on the album The Sky Is Falling and I Want My Mommy the following year. Biafra also provided lyrics for the song "Biotech is Godzilla" for Sepultura's 1993 album Chaos A.D..  In 1999, Biafra and other members of the anti-globalization movement protested the WTO Meeting of 1999 in Seattle. Along with other prominent West Coast musicians, he formed the short-lived band the No WTO Combo to help promote the movement's cause. The band was originally scheduled to play during the protest, but the performance was canceled due to riots. The band performed a short set the following night at the Showbox in downtown Seattle (outside the designated area), along with the hiphop group Spearhead. No WTO Combo later released a CD of recordings from the concert, entitled Live from the Battle in Seattle.  As of late 2005, Biafra was performing with the band The Melvins under the name "Jello Biafra and the Melvins", though fans sometimes refer to them as "The Jelvins." Together they have released two albums, and have been working on material for a third collaborative release, much of which was premiered live at two concerts at the Great American Music Hall in San Francisco during an event called Biafra Five-O, commemorating Biafra's 50th birthday, the 30th anniversary of the founding of the Dead Kennedys, and the beginning of legalized same-sex marriage in California. Biafra is also working with a new band known as Jello Biafra and the Guantanamo School of Medicine, which includes Ralph Spight of Victims Family on guitar and Billy Gould of Faith No More on bass. This group debuted during Biafra Five-O.  In 2011, Biafra appeared in a singular concert event with an all-star cast of Southern musicians including members from Cowboy Mouth, Dash Rip Rock, Mojo Nixon and Down entitled, "Jello Biafra and the New Orleans Raunch & Soul All Stars" who performed an array of classic Soul covers to a packed house at the 12-Bar in New Orleans, Louisiana. He would later reunite with many of the same musicians during the Carnival season 2014 to revisit many of these classics at Siberia, New Orleans. A live album from the 2011 performance, Walk on Jindal's Splinters, and a companion single, Fannie May/Just a Little Bit, were released in 2015.

What role did he have with other bands?
In the early 1980s, Biafra collaborated with musicians Christian Lunch and Adrian Borland (of The Sound) for the electropunk musical project
