Disturbed is plenty OK and I've been a fan ever since they covered "shout".
Dave's toned down the cookie monster singing and it seems he's actually got some good technique and expression.
This song is also a warning and the singer goes from crystal clear, then falsetto, and then full on hard rock texture and belting.
Epic performance.
