There is a total lack of musicianship in new metal bands, they just bask in the glory of Drop D tunings and 1 finger power chords. And then for vocals they just yell as loud as they can, I can give credit to the guys who have a really devilish growl like Muhhamed (sp?) Suicmez, and he can play a million times better then most new bands while growling.
I actually blame magazines for alot of this, they praise every new band like gods and then make guitar players (zakk wylde) seem way better than they are.
