The band would continue to generate momentum on the Los Angeles music scene, notably performing headline shows at Al's Bar, Pedro's, Largo and The Actors' Gang studio. Maynard James Keenan, lead vocalist of the band Tool, had also met Cross on the Los Angeles scene, and therefore had also become involved in "Mr. Show". Keenan invited Black and Gass to support three Californian Tool concerts in December 1995. Tool was the first large act that Tenacious D were a support act for. Black had previously 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.
