An exceptionally badass 80's thrash metal band from Los Angeles, California. Their music is just as heavy, if not, HEAVIER, meaner, and more intense than Slayer's music. Dynamic riffage, very fast and brutal drumming from Gene Hoglan(now playing drums for Strapping Young Lad, and pretty damn evil lyrics as well.
You just have to listen to their best album "Darkness Descends" to believe me. It absolutely owns the shit out of Slayer's "Reign in Blood."
