Mr. Bungle was an American experimental rock band from Eureka, California. The band was formed in 1985 while the members were still in high school, and was named after a 1950s children's educational film regarding bad habits which was later featured in a 1981 Pee-wee HermanHBO special. Mr. Bungle released four demo tapes in the mid to late 1980s before being signed to Warner Bros. Records and releasing three full-length studio albums between 1991 and 1999. The band toured in 2000 to support their last album before going on hiatus; ultimately revealing that they had dissolved in 2004. Although Mr. Bungle went through several line-up changes early in their career, the longest-serving members were vocalist Mike Patton, guitarist Trey Spruance, bassist Trevor Dunn, saxophonists Clinton "Bär" McKinnon and Theo Lengyel, and drummer Danny Heifetz.
