Primus is all about Les Claypool. There isn't a moment on any of their records where his bass isn't the main focal point of the music, with his vocals acting as a bizarre sideshow. The music of Primus has been described as alternative rock, alternative metal, experimental rock, funk rock, funk metal, progressive rock, and thrash-funk.
