Primus is an American rock band formed in '84 with guitarist Larry "Ler" Lalonde, vocalist and bassist Les Claypool, and drummer Jay Lane. The band has released four studio albums, and the most successful early single was "Wynona's Big Brown Beaver." With irreverence as the central theme, it was fitting that the band created the original theme for "South Park" in '97.
In 2003, Claypool and Tim Alexander produced the DVD, "Animals Should Not Try to Act Like People." They released their seventh album, Green Naugahyde, in September, 2011.
