for instance, ive seen the tech metal band archspire a bunch of times and no matter where they play 99% of the time they sound as good and clear as their album. same deal with fallujah, their live sound was perfect, like listening to an album. most metal bands just sound ok but its usually quite hard to hear the actual notes being played. its got to be more than just using good gear and less gain and lots of mids. what else could it be? it just sounds too perfect.
