I once read an interview with steve vai, and learned something i never forgot - what makes his playing (and satch too IMHO) unreal is the fact that he has removed all the barriers between his heart / soul / brain (call it what you will) and the guitar.
Am I the only one that things Steve Vai is a major pothead? I've read articles where he talks about just sitting there and playing one note for hours. Now, I understand the theory behind it..but I think the only way I could ever get myself to do that would be after a couple bowls of nl ;(
