Trevor Dunn is a bassist out of the San Francisco Bay Area, where he works with the best of the locale's creative improvisers and musicians such as Rova Saxophone Quartet, Mr. Bungle, clarinetist Ben Goldberg, and more. He has performed a variety of styles, with a background in punk and death metal, contemporary classical, blues, and jazz -- both standard and free. Dunn is co-founder and composer of the avant-rock band Mr. Bungle (with vocalist Mike Patton), which started in 1985. Through the '90s, Dunn has also been active, rock-wise, in the Secret Chiefs 3, a side project with two other Mr. Bungle members, which has released two CDs. In addition to playing in this group, Dunn is a member of the jazz outfits Graham Connah's Sour Note Seven, Junk Genius, and various Ben Goldberg groups. At the end of the '90s, Dunn was working on a new hardcore project called Fantomas with Patton, Slayer's Dave Lombardo, and Buzz Osbourne of the Melvins, and leading his own jazz group, Trio-Convulsant, whose first CD came out in 1999 on Buzz Records.
