Darby Crash (formerly Bobby Pyn; born Jan Paul Beahm; September 26, 1958 – December 7, 1980) was an American punk rock vocalist and songwriter who, along with long-time friend Pat Smear (born Georg Ruthenberg), co-founded the punk rock band the Germs.
 He committed suicide by way of an intentional heroin overdose.
 In the years since his suicide at the age of 22, the Germs have attained legendary status among punk rock fans and musicians alike, as well as from the wider alternative rock and underground music community in general.
 Crash has come to be revered as a unique and talented songwriter; his myriad literary, musical and philosophical influences, which varied from Friedrich Nietzsche and David Bowie to Charles Manson and Adolf Hitler, resulted in lyrics that were unusually wordy and impressionistic in the realm of punk rock at the time, immediately setting Crash and his band apart from most other Los Angeles punk groups that sprang up in the late 1970s.
The Insaints were an American punk rock group from Modesto and later San Francisco, California, fronted by controversial vocalist Marian Anderson from 1988-1994.

 The Insaints made Bay Area headlines when Anderson was arrested for lewd conduct after an infamous 1993 performance at 924 Gilman Street in Berkeley, CA.
 The charges were eventually dropped after a yearlong legal battle, but the band broke up in 1994.
 In 2001, Anderson died of a heroin overdose at the age of 33.

 Founding drummer, Jack Irons returned the band the previous year to finish out the band's tour and record the next album, The Uplift Mofo Party Plan, which ended up being the only album and full tour to feature the four founding band members: Anthony Kiedis, Flea, Hillel Slovak and Irons.
 It was the band's biggest tour at the time and featured their first trip to Europe.
 Kiedis, who started to develop a major drug problem on the previous tour, started to fall deeper into his addiction and Slovak's addiction to heroin only grew stronger as well.
 Slovak died of a heroin overdose a few weeks after the end of the tour on June 25, 1988.
 The surviving three members regrouped for a small boat trip with then manager, Lindy Goetz.
 It was there that Irons decided he could no longer deal with being in the band and Slovak's death was too hard for him to handle so he decided to quit the band again, this time for good.
