Initially known as Heresy, this thrash metal outfit hailed from Tucson, Arizona, USA. The band was formed in 1987 by vocalist Brian Zimmerman and guitarist Chris Lykins. Recruiting Rick Skowron (guitar), James Gulotta (bass) and Tim Kelly (drums), they recorded a demo "Chemical dependency", the same year. This attracted the attention of thrash specialists Roadrunner Records, who immediately recognized them as a band with great potential. "Socialized Hate" was an impressive debut, featuring heavy-duty riffing, screaming guitars and thoughtful lyrics. Their second album "Violent by nature" saw some musical progression, with the material showing a greater awareness of melody and a slightly less extreme approach.
