Primus is a San Francisco-based band formed in the mid-1980s by 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 30 years) and many different drummers (although Tim Alexander, Bryan Mantia and Jay Lane were the only ones who recorded with the band) in the past.
Their music has proven difficult to define; while usually considered by critics to be funk metal or alternative metal, Primus has been called everything from "thrash funk" (as the band blends funk-style bass technique with thrash influenced guitar riffs and songs tempos), to "alternative rock" to "the Freak Brothers set to music." Les Claypool himself once described their music as "psychedelic polka." Thanks to the diversity of their sound they have been able to gain fans from nearly all rock subgenres.
