Tenacious D is an American comedy rock duo, formed in Los Angeles, California in 1994. It was founded by actors
Jack Black and
Kyle Gass, who were part of The Actors' Gang theater company at the time. The duo's name is derived from "tenacious defence" - a phrase used by NBA basketball sportscaster
Marv Albert. In 2000, they signed with Epic Records, and the year after released Tenacious D, their debut album featuring a full band - this including
Dave Grohl on the drums. The first single, "Tribute", has since achieved cult-status.
