I'd probably say Dead from Mayhem. He was definitely interesting.
And Wayne Knupp, the original singer of Devourment.
Maybe Vitek from Decapitated. Got their first cd, back from when he was 15, and he was amazing back then. Guy would probably have been one of the best death metal drummers if he had gotten to stay alive.
