When I saw what it was I thought oh God, I won't be able to cope with this.... but it was indeed cool.
Interesting what they were saying early on about how difficult it is to dissect a part they wrote. That's something I've always had massive problems with. If I make something up, the fingering and timing just takes care of itself and it sounds OK. But if I try to learn a well-known riff or song, it feels stiff and unnatural... it's almost like trying to put yourself in someone else's brain. Stating the obvious really, I suppose, but interesting to hear it discussed.
I'm not sure I ever believe these guys who insist they can't play a major scale though.... :?
