I wouldn't categorize Skeletonwitch and Goatwhore as DM, more on the thrash side of things. Behemoth maybe/kinda/sorta.
I remember being on a house boat trip for a bachelor party years ago, and it was most jocks and people who I don't much car for. Anyways, some of the guys were into Metallica, so every once in awhile the dance music shite was broken up when they put it on. The next day this dude was yelling and screaming about someone playing death metal the night before, and he was going to freak out and kick some ass if "anyone plays any death metal today!!!". Much lulz, so angry.
