Nick Oliveri

Nick Steven Oliveri (born October 21, 1971) is an American musician from Palm Desert, California. He is widely known for his role as bass guitarist with Queens of the Stone Age and before that, Kyuss. His aggressive playing style uses a pick to get a punchy, brutal tone. During the 2001 Rock in Rio show, bassist Nick Oliveri was famously arrested after performing on stage naked, with only his bass guitar covering his genitals.

The whole 'naked bar a bass guitar' thing was fine right up until Oliveri invested in a Dan Armstrong plexiglass bass. Anyhoo...
