Tomahawk is an experimental alternative metal/alternative rock supergroup from the United States. They formed in 2000 when Fantômas, ex-Mr. Bungle and Faith No More singer/keyboardist Mike Patton and ex-The Jesus Lizard guitar player Duane Denison started swapping tapes with the intention of collaborating. Denison then recruited ex-Helmet drummer John Stanier, while Mike Patton recruited Melvins/Cows bass player Kevin Rutmanis into the group.
