Jack Black and Kyle Gass initially met in Los Angeles in 1986 at their teacher's house, both members of The Actors' Gang theater troupe. Black admits that, due to animosity, he and Gass didn't initially see eye-to-eye, 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 Festival in 1989. They were performing Tim Robbins' and Adam Simon's play "Carnage". The two befriended during the trip, notably climbing Arthur's Seat on a day off.
