Sludge metal. It's good;

Anyone, any more reccos on the post metal + sludge bands such as Intronaut and Isis?

Battle of Mice - A Day of Nights

This album is creepy as hell. The woman on vocals is very odd... She goes from almost sounding like Avril Lavigne, to a mental patient in a single track.

Other rec's.
Discombobulation - Roman's Melancholia (good album, but the last two tracks drag it down)

Neurosis - everything here is solid... although I really dont like them as much as some of the other big names in the genre.

Pelican - these guys are instrumental, but are absolutely fantastic.
 
Grief
Crowbar
Rwake
Iron Monkey

Edit: :OMG: Ill have to find more now.

Acid Bath
-(16)-
Black Cobra
Unearthly Trance
 
the southern us doom/sludge is my favorite. i posted a few more just because you post jumped me.
 
For the sake of double posting, I'd like to ask why various people started up all these subgenre threads when we already have Albums currently kicking your ass and the band recommendations forum.

So you create a Sub-genre thread to ask why so many people are creating sub-genre threads? :lol: Looks like your asking for validation.
