Leslie Edward "Les" Claypool is an American musician and writer, best known as the lead vocalist and bassist in the band Primus. Claypool's playing style on the electric bass mixes tapping, flamenco-like strumming, whammy bar bends, and slapping. He is widely regarded as one of the best rock bass players of all time.
Claypool has also self-produced and engineered his solo releases from his own studio, "Rancho Relaxo". 2006 saw the release of a full-length feature film Electric Apricot written and directed by Claypool as well as a debut novel South of the Pumphouse.
