Machine Head were formed on October 12, 1991, in Oakland, California by vocalist/guitarist Robb Flynn and bassist Adam Duce. Flynn had recently parted ways with Vio-lence after a physical fight between the band members and a local gang. He still had a desire to write music and along with Duce recruited guitarist Logan Mader and drummer Tony Costanza to form Machine Head. The band's name was thought of by Flynn because it "sounded cool", despite the popular belief that it came from the Deep Purple album of the same name. The band started jamming in a local warehouse shared with four punk rock bands. Machine Head recorded a demo in a friend's bedroom, funded with US$800. A record executive representing Roadrunner Records listened to the demo and signed the band.
