Mine might be a little heavy for some
I can bring the heavy Vio-Lence
Best known as the former band of Rob Flynn and Phil Demmel of Machinehead, these guys were a great 80s thrash band. Yes I know the vocals are god awful, even by thrash standards. Armored Saint
Old band of John Bush, who did vocals on Anthrax's best album Sound of White Noise. They were doing groove metal like Pantera and other 90s bands in the early 80s. Grief
Raw, dirty, sludge like EHG. One of the few bands that can match EHG's level of nihilism in this genre. Crisis
Their singer lead the way for women in metal. She can do harsh vocals and clean vocals and is actually good at it. Bands like In This Moment and most other female fronted metal bands are just a cheap imitation. The band is really good too.
Fun Fact: I saw Crisis in Breaux Bridge in 1998. I stood by Caryn the whole show. She's about 4 feet tall.
