Metal with emphasis on bass

I'm looking for some good bass-heavy metal bands, or songs were the bass is more prominently featured than the guitars. Not precisley looking for clipping, raw bass, but for some deep hulking atmospheres. I'd say similar to Sunn o)) but less doomier.

Any recommendations?

Venom

Om

and a little further afield, i.e. not hulking atmospheres etc but definitely bass-intensive and a must for anybody who likes a good bassist: Atheist

Warhorse As Heaven Turns to Ash

They're the only band tuned lower than Sunn0))). Sunn0))) is in A flat. Warhorse tuned to G.

Extreme :)

It's really beautiful and remarkable how they make the guitar sound. The strings are so slack, he had to invent a new way of playing really. It's very effects driven...
