Well, there's lots of good stuff being mentioned again and turns out all the bands I haven't heard are the UK ones, haha (except for Plague.)
I just feel like I need to be more precise, I'm not looking for powerviolence, weird or sludge-y bands, I'm looking for stuff that makes you want to floorpunch like mad and destroy everything. I've been trying to make a mixtape for my band's drummer because he likes moshing hardcore but the "bad" kind. I just want to find some bands that are dark, heavy, straightforward and with mean breakdowns. So far I put Gehenna, Disembodied, Undertow, Harvest, Bloodlet, Threadbare, The Swarm, Left For Dead, Damnation AD, Grounwork, Acme and Turmoil on it. It's pretty solid so far in my opinion. I just need 4 or 5 more bands. Sorry for being picky
Also, I absolutely HATE Integrity.
More power to me.
