Often used to describe bands like Pantera and Exhorder. With mid-tempo riffs similar to those found in Thrash Metal and a tendency to focus more on groovy syncopation and heaviness than outright speed.
Right, I gotcha. I was into some death and grindcore when it first became a thing. I think I was into it more because at that time I just wanted the most extreme stuff possible - I hadn't heard anything like that before, and as a thrash guy, the crazier the better. Like early Obituary, Carcass, Napalm Death, Morbid Angel, etc.
I've been into metal since '84 so I guess that's 34 years. Scary. Taste went from softer to harder and now back to somewhat softer again.
