Machine Head is an American heavy metal band from Oakland, California. Formed on October 12, 1991, the group was founded by Robb Flynn and Adam Duce. There have been 4 member changes since their inception. The current lineup of the band comprises Flynn (vocals, guitar), Duce (bass), ex-Vio-Lence guitarist Phil Demmel (guitar), and Dave McClain (drums). Machine Head is one of the pioneering bands in the New Wave of American Heavy Metal. Machine Head was formed by member Robb Flynn, previously part of the bands Forbidden and Vio-lence. Flynn felt musically unfulfilled with Vio-lence and requested to start a side project. When his request was denied, he left the band and formed Machine Head in 1992 with Adam Duce, Logan Mader and Tony Constanza. Though the band's first album, Burn My Eyes, was a big success in Europe where it garnered attention on MTV's Headbangers Ball, in America (with HBB taken off the air during the grunge movement) Machine Head would not have success until later albums.
