ok
first of all, SLEEP are nowhere near the melvins. there a stoner doom band, with a bad sound (Dopesmoker is ok tho)
second of all what do you mean favorite melvins-sounding band? I mean, bands only sound like the sludgey / ozma / gpt melvins era. then, they started to do shit that nobody even tries to imitate.
third of all, I think you guys should check BURNING WITCH.
some of you might find it boring, like almost every O'Malleys project, but if your into SUNN, you would love the WITCH!!!! one of the heaviest bands if you ask me.
you probably wont hear the melvins in them at the very first listen, but if you listen carefully you will. I think THE MELVINS and EARTH were a big influence to Omalley and you can hear his heavy-ass droning riffage whether its the blackdoom act THORRS HAMMER (beauty!!!!!!!), THE WITCH, KHANATE, OR SUNN.
basiclly TH, BW and KHNT are SUNN with drums. Im not saying it as a bad thing tho. its fuckin HEAVY!
otherwise if some of you havent already, check EYEHATEGOD, HARVEY MILK and NEUROSIS!!!!!!!!!!
