Geoffrey Lyall (born in 1949 in Detroit, Michigan), better known as Klaus Fluoride, is best known as the bassist for the San Francisco, California, punk rock band Dead Kennedys from the group's inception in June 1978 until the band's breakup in March 1986, although he also produced four solo albums during the 1980s and 1990s.
Fluoride began working on a solo album following the release of Dead Kennedys' second album, 1982's Plastic Surgery Disasters, coming out with the 12" single "Shortnin' Bread" (with "The Drowning Cowboy" as the B-Side) in 1982 and the EP Cha Cha Cha With Mr. Fluoride in 1985.
After the breakup, Fluoride returned to his solo career, releasing Because I Say So in 1988 and The Light Is Flickering in 1991, the latter album including the song "Dancing with Shauna Grant".
Fluoride also works in the studio as a producer and mixer and has done projects with the Hi-Five, Ape, and Bad Posture. He and his former band-mates also became embroiled in a protracted lawsuit...
