Poison Idea is an American punk rock band formed in Portland, Oregon in 1980. The band originally dissolved in 1993, but has been playing intermittently since 1998.

Poison Idea was formed in 1980 by vocalist Jerry A. (aka Jerry Lang). The initial lineup consisted of Jerry A., Chris Tense (guitar), Glen Estes (bass), and Dean Johnson (drums). Inspired by Black Flag and other early Southern California hardcore acts, they were further influenced by Discharge and Los Angeles's the Germs. Germs singer Darby Crash's influence on singer Jerry A., vocally, lyrically, and philosophically, was considerable, and Poison Idea followed the Germs’ extremist punk ethic. Tense, who previously had played with Jerry in a group called the Stand, was replaced within a year by Tom "Pig Champion" Roberts (guitar), formerly of the Imperialist Pigs.
Poison Idea’s debut, 1983's Pick Your King EP was a short, lo-fi blast of hardcore fury. The jacket featured a "choice" of two kings, Jesus (front cover) and Elvis Presley (back cover).

In 1984, Chris Tense returned to the band, this time on bass, replacing Glen Estes (later of Portland, Oregon punk/metal band Final Warning), and the group released the Record Collectors Are Pretentious Assholes 12” (the cover features Pig Champion’s substantial vinyl collection). The record found the band incorporating subtle rock elements into their music, which was further honed on their contributions to two 1985 compilations, “Laughing Boy” on the Drinking is Great EP (on which appeared other Oregon punk bands Final Warning, Lockjaw and E-13), and “Typical” and “Die on Your Knees” on the legendary Cleanse the Bacteria LP (compiled by Pushead for his own Pusmort label).

With the release of 1986’s Kings of Punk LP, Poison Idea had fully moved beyond the breakneck hardcore of their early records to a potent, driving and ultimately more intricate and sophisticated hardcore/hard rock fusion that incorporated the accessibility of hard rock without sacrificing the power of hardcore.

Following the release of Kings of Punk, the band went through several rapid lineup changes (mostly in the rhythm section), and then added lead guitarist Eric "Vegetable" Olson, a gifted musician who wrote many PI tunes during his tenure in the band (even contributing a piano vamp on one track). The band then released War All the Time (named for the Charles Bukowski book) in 1987. War All the Time and the EPs that followed (the Getting the Fear 12" and the Filthkick 7") found them further developing the rock/hardcore sound first established on Kings of Punk, which they would hone in 1990 with Feel the Darkness.

Around this time, after numerous lineup changes, PI had convened one of their more stable lineups in Jerry A., Tom "Pig Champion" Roberts, Charley "Myrtle Tickner" Nims (bass) and Steve "Thee Slayer Hippy" Hanford (drums), with Kid Cocksman and then Aldine Strichnine on second guitar. By this time, their drinking habits and hard living were beginning to catch up with them: the band weighed in at about 1,300 lb. collectively, and Pig Champion in particular was very fat, often having to play sitting down. They also established their own record label in 1989, American Leather (named for the Germs song), and released two records the same year: a reissue of their 1982 demo Darby Crash Rides Again and the Discontent 7”.

In 1990, the band released Feel the Darkness. After the release of Feel the Darkness, Aldine Strychnine was thrown out of the band, and Mondo returned this time on guitar, for the 1991 tour. PI then released Blank Blackout Vacant in 1992, and, before seemingly splitting in 1993, they released We Must Burn.

When Pig Champion left the band in 1993, shortly before the recording and release of the live album on Your Choice Records produced by Tobby Holzinger, PI effectively called it quits. Jerry A pursued a solo project called Gift with his wife and Thee Slayer Hippy, and in 1998 the original line-up reunited for a 7" EP on released on Taang! (who reissued their early catalogue), but broke up following an aborted tour.

erry A reformed the band in late 1999 with the line up featuring Tom "Pig Champion" Roberts (guitar), Matt Brainard (guitar), Chris Carey (bass) and Chris Cuthbert (drums), and after breaking in the new lineup the band toured the east coast in 2002 including an appearance at CBGB's. Also a couple of trips to Texas and California. Matt Brainard was busy with DEFIANCE back then and decided that two full-time touring bands was too much, so he elected to leave the band. Jimmy Taylor was hired on as guitarist for PI as the band was planning a 6 week tour of Europe, he ended up being a permanent member of the band. They toured Europe twice in 2003 and 2004, with Eric Eggroll on guitar during 2003 and Joe Spleen (The Gits) during 2004 filling in for Pig on the road. In 2004 PI was invited to go on a tour in Japan as a 4 piece with Japanese punk legends Forward. They were well received in the other countries they toured, inspiring the band to put together a new record.

Back home in Portland, the new line up (Jerry A, Pig Champion, Jimmy Taylor, Chris Carey and Chris Cuthbert) began working on material which later became "Latest Will and Testament", recorded in 2005 at Smegma recording studio in Portland OR.

On January 31, 2006 guitarist Tom "Pig Champion" Roberts died aged 47 at his home in Portland of undetermined causes, although he had been suffering from the flu and an untreated kidney infection. The band had recorded the new record and it was ready for release when he died. Pig wanted the record to be called Latest Will and Testament, a name that the rest of the band liked. After Tom’s death Jerry commented that Pig probably knew something that the rest of them didn't. The album was released in May 2006 on Farewell Records. The band did not play a record release show, or any show for over a year as they tried to get used to the idea that their friend was gone.
