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 members of The Actors' Gang theater company at the time. The duo's name is derived from "tenacious defense", a phrase used by NBA basketball sportscaster Marv Albert.
