Les Claypool is one of the all-time best slap bass players. One of his early heroes was Geddy Lee. "When I saw my first Rush concert, I spent the whole time watching Geddy's hands," Claypool told Bass Player Magazine. "There were so many things I didn't know; I didn't even know there were such things as roundwound strings. I'd had that Memphis a year and a half without changing the strings, and here I was trying to sound like Geddy Lee and Chris Squire." Years later he developed his signature funky, slap bass sound that fueled his band Primus and his supergroup Oysterhead, which he formed in 2000 with Police drummer Stewart Copeland and Phish frontman Tren Anastasio.
