S.A.SLAYER, originally known simply as SLAYER, was an American heavy metal band formed in San Antonio, Texas in 1981 by the former Blitzkrieg guitar duo Robert "Bob Dog" Catlin and Art Villareal, bassist Don Van Stavern, drummer Dave McClain, and vocalist Chris Cronk ( Fates Warning, Jag Panzer, Karion, Talisphere, Target 7). The latter was soon replaced by Steve Cooper and the band signed a record deal with local upstart label Rainforest Records and proceeded to record six songs for a proposed EP at B.O.S.S. Studios with producer/engineer duo Bob O'Neill and Rick Shrieves. The Prepare to Die EP was released in 1983 to excellent reviews, and "Slayer", as they were known at the time became one of the top metal draws of the Texas scene.
