Blind Illusion

Blind Illusion was a legendary SF Bay Area metal band for years, going through many lineups and style changes prior to their first release (progressive rock among them). The original lineup (formed around 1979) consisted of vocalist David Godfrey (later of Heathen), guitarist Mark Biedermann, bassist Alvin Petty, and drummer Bret Hern. By the time of The Sane Asylum, only Biedermann remained, and in fact Les Claypool and Larry LaLonde departed soon afterward to form Primus. The Sane Asylum was a thrash album -- a very good one at that, highlighted by Les Claypool's inventive basswork (a style he would fully develop later in Primus). Biedermann has been involved with many other bands over the years, contributing on albums by Blue Oyster Cult and Heathen (and others I'm sure). Currently he is living in northern California and amongst his projects are re-releasing The Sane Asylum, releasing the unreleased second album (The Medicine Show, apparently featuring Claypool and LaLonde), recording a third Blind Illusion album, and assorted other metal music projects.
