Background: Tenacious D is an American rock duo that was formed in Los Angeles, California in 1994. Composed of lead vocalist and guitarist Jack Black and lead guitarist and vocalist Kyle Gass, the band has released three albums - Tenacious D (2001), The Pick of Destiny (2006) and Rize of the Fenix (2012). Tenacious D's studio releases, and (as of 2006) its live performances, feature a full band lineup, including such musicians as guitarist John Konesky and bassist John Spiker. Drummer Dave Grohl (Foo Fighters, Nirvana) has played on every studio album.
Context: Jack Black and Kyle Gass initially met in Los Angeles in 1985, both members of the theatre troupe, The Actors' Gang. Black admits the duo did not see eye to eye due to animosity between the two, as Gass was the main musician for the Actor's Gang and felt threatened by Black. The Actor's Gang travelled to Edinburgh, Scotland for the Edinburgh Fringe in 1989. They were performing Tim Robbins' and Adam Simon's play Carnage. The two became friends during the trip, and eventually became best friends, with Black regularly visiting Gass' Cochran Avenue studio apartment, in the deal that Gass would teach Black to play guitar in return for food, mainly from fast-food chain Jack in the Box.  Between 1989 and 1994, the two would work at The Actor's Gang together, and would collaborate in productions. Gass and Black wrote their first song in 1994 after Black had been dumped by a girlfriend, this song was scrapped aside from the pair playing it at later Tenacious D concerts as a joke and referencing it in interviews. Their second song came about when Black was listening to Metallica's "One" in 1994 and told Gass that it was the "best song in the world". Gass told Black that they couldn't write the best song in the world but Black put a twist on it and said they could write a tribute. Gass played an A minor chord at his apartment and the two spent three full days crafting the song, when it was done Gass mentioned "they knew they had something". The song made the duo realise their comedic potential.  At their first concert, at Al's Bar (now an apartment complex), the band performed the live debut of "Tribute", their only song at the time, and the duo also gave the audience the chance to vote for their name. Black and Gass gave them the choice between "Pets or Meat", "Balboa's Biblical Theatre" and "The Axe Lords Featuring Gorgazon's Mischief" (Gass' personal favorite). "Tenacious D"--a basketball term used by commentators to describe robust defensive positioning in basketball --did not get the majority of votes, however, but according to Black "we forced it through". The venue had become a hotbed for upcoming bands due to the success of Nirvana and the Red Hot Chili Peppers, so much so that in attendance was David Cross who later cast Jack Black in his sketch comedy television series, Mr. Show.  In 1995, the band supported the band, Tool, during their Californian leg. Black attended UCLA with director Jason Bloom, therefore, when Bloom was made the director of 1996's Bio-Dome, Black and Gass were invited to perform a short song in the film. The two wrote the song, "5 Needs", and this was their first on-screen appearance as Tenacious D. Black and Gass also performed their song "Jesus Ranch" in the 1998 film, Bongwater. Tenacious D recorded their songs "Tribute", "Kyle Quit the Band", "Krishna" and "History" and released them in a demo tape called Tenacious Demo, in the mid-1990s with Andrew Gross, distributing it to various record companies until HBO offered them a TV show based upon the tape and Black's work on Mr. Show.
