I'm reading and hearing quite a lot of good stuff about these guys. I'm a massive fan of Kyuss/Melvins/Queens/Brant Bjork/PJ Harvey/Sabbath - I like stuff with a real groove. I don't know if that helps....

Anyway, where should I start? I gather their sound has changed a lot throughout their discography. I'm really into the darker side of heavy rock/stoner rock but some of their stuff sounds more like what I would call heavy blues rock.

Thanks in advance!
