Machine Head entered Fantasy Studios in Berkeley, California to record its debut album "Burn My Eyes". Not long into production, Constanza left the band and was replaced by Chris Kontos. Most of the songs on the album were songs written by Flynn and Duce during the time Flynn was not in a band, about "being pissed off" from his previous struggles in Vio-lence, as well as both of their battles with illegal drugs. Produced by Colin Richardson, the album was released on August 9, 1994. The album shipped nearly 400,000 copies worldwide, becoming Roadrunner Records' best selling debut album. Allmusic reviewer John Franck stated ""Burn My Eyes" is a bone-shattering exercise in brutality".
