There are four bands called TRIAC. The first is a brutal three piece grindcore band from Baltimore, Md. featuring Jake Cregger on drums, Chadd Heathen on bass/vocals, and Kevin Bernsten on guitar/vocals. "Baltimore's Triac juxtapose classic Amphetamine Reptile muscle with modern powerviolence, resulting in a crushing fusion of raw grind and noise-rock forcefulness punctuated by massive drumming & filthy bass". 2003 - Formed from the ashes of THE INDEX by Jake Cregger, Mark Sloan, and Richard Johnson.
