yeah, you don't get to be on major national tours if you don't have the chops.
I was telling the guys I was with yesterday that if I was in a band and saw the level of intensity and precision these guys play with, I would probably really need to step up band practice time. They're just a machine.
One thing though ... I would be curious how this stuff translates in big arenas when they play with Metallica. Something tells me, not so well. Their stage presence and intensity needs the intimacy of a smaller place.
