Im an already avid listener of Brutal Slam Death but I dont think i can ever get enough of it. Im looking for something with higher growls and squeals if that makes sense? Something like Field Dressed, or maybe even along the lines of GO-ZEN. I want something that makes me think of being in a pig slaughterhouse. Anything that even has lower pitched vocals will be greatly appreciated nonetheless. The more undergroud, the better.

I'm guessing you're already ahead of those who're seeing your post so they don't have much to recommend. I saw your title but my suggestions only extend as far as the obvious, like Devourment, Kraanium, etc. I didn't know who Field Dressed or Go-Zen were until I looked them up. Good luck though!
