(born January 30, 1968 in Eureka, California) is an American musician. His primary instrument is bass and double bass. Dunn has a degree in music, learning double bass at college. Dunn began playing bass as a teenager. In high school, 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. His playing on Mr. Bungle's Disco Volante displayed Dunn's maturity as a player as the compositions shift from different musical stylings several times in every song. Dunn prefers to play simple bass lines in other's compositions choosing to support song structures. He is (or has been) a member of:

* Mr. Bungle (Now defunct)
* Fantômas
* Secret Chiefs 3
* Trevor Dunn's Trio-convulsant
* David Krakauer's Klezmer Madness

He has contributed to or played with:

* John Zorn's Electric Masada
* John Zorn's Naked City
* Tin Hat Trio
* The Melvins
* Matisyahu
* Many other Bay Area and New York artists

In the early days of Mr. Bungle he played an Ibanez bass built sometime in the 1980's, and later on, he used a Peavey Fretless, an Alembic Europa 5-String and a double bass. He mostly uses a 1975 Fender P-Bass tuned to BEAD for Fantômas. He plays double bass with Trevor Dunn's Trio-convulsant.

Like the other members of Mr. Bungle, Trevor Dunn is reluctant to talk about what exactly caused their break-up in 2000 (Dunn is especially hesitant about the subject). For that matter, Dunn is reluctant to talk about Mr. Bungle in general, though he claims to have enough material for a book about the band (and enough unreleased songs for a companion album). He initially stated that he was going to release a book, but it has since fallen into obscurity ("That book concept is FAR from being a reality. It's just a hazy thought in my mind at this point. Part of that haze includes demos, rehearsals, prank phone calls, unused photos, etc. The amount of unseen/unheard material I have collected over the years is somewhat baffling. Believe me, it's not going to happen anytime soon."). Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
