Yes, but tightened muscles, shallow breathing and a racing mind don't do anyone any favors either. Over-motivation in the heat of the moment leads to mistakes because of heightened negative feedback loop sensitivity. (Or some such. I try not to make too much stuff up as I go along. I really do. But sometimes it just gets away from me.)
Beethoven's 9th or anything by the Russians...Rachmaninov...etc. Rach actually reminds me a lot of Metallica. He just needed James Hetfield's voice to be a 100 years ahead of himself.
