Cattle Decapitation originally formed in San Diego in 1996. Originally, the lineup featured David Astor on bass and Gabe Serbian on drums -- both of whom were then also members of the Locust -- as well as an unknown guitarist/vocalist, who allegedly vanished without the other members knowing anything of his whereabouts. Seeking a replacement on vocals, the band turned to Travis Ryan, who had actually been playing drums for another San Diego metal band, Strangulation, in addition to serving as vocalist in a gore metal band called Anal Flatulence. With Ryan on board, Astor moved from bass to drums, and Serbian moved from drums to guitar. This lineup quickly released two albums, the Human Jerky LP (on the Nevada label Satan's Pimp) and the Homovore CD/LP.
Next, they added a bassist, Troy Oftedal, with whom they recorded their third full-length, To Serve Man, released in the fall of 2002 on Metal Blade, a move that would expose them to more of a death metal-oriented audience (as opposed to the hardcore/grindcore one that they had mostly been playing to before). Also in 2002, the band added a second guitarist, Josh Elmore (formerly of 7000 Dying Rats), who eventually took over as the band's sole guitarist after Serbian left in order to devote himself more fully into the the Locust. (Serbian plays drums in the Locust, replacing Astor, who ironically had left the Locust so that he could more fully devote himself to Cattle Decapitation). Astor left after To Serve Man and was replaced by Creation is Crucifixion drummer Michael Laughlin for the 2004 release Humanure. The members of Cattle Decapitation are involved in several side projects, among them Oftedal's punk/metal band DisreantiyouthhellchristbastardassmanX, Ryan's noise project 5/5/2000, and UUM, another noise project involving both Ryan as well as Oftedal. ~ William York, All Music Guide
