How did we get from the ball-grabbing ear-piercing top of the vocal range metal vocals of the likes of Zeppelin et al to whatever the hell sludge is? And seriously, doesn't it hurt the singers throat? Oh, and Ben out of Weapon did do a similar shouty thing but I take it they're not sludge then? Basically it went from doom like sabbath and saint vitus, and it got heavier and more distorted. And no, MMW were definately not sludge.
