Dig sludge? Check out THOU.

They bring the magick. You can download alot of their stuff for free on the website. I recommend doing so, 'cause, once again, they bring the magick.

 

Sounds decent

 

"By Every Hand Betrayed" and "I am the Leviathan" are both stellar.

 

I've known about them for a while, but their only song that I like is "Acceptance." I'm not much of an extreme sludge fan.

 

Not half bad
