Slam Death Metal Bands.

I only know one SDM band and thats Disfiguring the Goddess and by god they are Godly and do god on everything Vocals <3!, Guitar!, and Drums omfg they their drummer does alot of Hyper blasts, Blast beats, and gravity blasts its insane!

for more proof checkout:
Axiom of the Weak
and!
Feeding of Nihility.
The cool thing about this band is that their vocalist is 18 years old.
And that vocals have no FX what so ever it's all straight gutterals.

Do you know any SDM bands?
