Primus

Primus is a rock band formed in California in the mid-1980s by two ex-members of thrash metal band Blind Illusion, Les Claypool and Larry Lalonde. Les (vocals and bass guitar) has been the only constant member. They have had two guitar players (although Larry has held onto the role for the past 20 years) and many different drummers (although Tim Alexander and Bryan Mantia were the only ones who recorded with the band, and Jay Lane was the only other one who had creative impact) in the past.
