Primus is a rock band from El Sobrante, California, helmed by bassist-singer Les Claypool. Ever since their 1984 formation, the band is noted for an unique funk-tinted sound that is described by Claypool as “psychedelic polka” and earned the “Primus” ID3 genre tag, and an irreverent approach, to the point their slogan was “Primus Sucks”.
