Butthole Surfers is an American rock band founded by singer Gibby Haynes and guitarist Paul Leary in Corpus Christi, Texas, in 1981. Incorporating elements of hardcore punk, psychedelia, heavy metal, avant-garde and performance art, their live shows has made heavy use of strobe lights, background films (of note, footage of penis reconstruction surgery) and naked dancers. The band has a well-reported appetite for recreational drugs, particularly psychedelics, an evident influence on their sound.
