High Quality Content by WIKIPEDIA articles! Trevor Roy Dunn (born January 30, 1968) is an American composer, bass guitarist and double bassist. Dunn came to prominence in the 1990s with the experimental heavy metal group Mr. Bungle. He has since worked in an array of musical styles, notably with singer and Mr. Bungle co-founder Mike Patton; with saxophonist/composer John Zorn; and with the group Secret Chiefs 3. After four years of studying the clarinet, Dunn began playing electric bass at the age of 13. His earliest musical influences included the Beach Boys, Blondie, Cheap Trick, and Kiss. In 1986, Dunn formed Mr. Bungle with vocalist Mike Patton and guitarist Trey Spruance. Mr. Bungle's early compositions mixed thrash metal, hard rock, and funk with an air of adolescent humor and vulgarity. With a background in metal, Dunn branched out his musical abilities playing jazz around San Francisco while immersing himself in different music. 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.
