My point wasn't so much that bands like AC-DC are not valid. What I was trying to get at is, that kind of music exists because you don't have to be an amazingly gifted and technical musician to make that kind of music. I'm not saying it wasn't original, or creative, only that it isn't particularly difficult music. So I was wondering if music like that only exists because there are musicians who are not as good as other musicians.
Maybe a better example would be someone like Green Day. Never once is there a guitar solo to speak of. So if all guitarists had amazing technical chops, then would Green Day's guitarist still enjoy playing power chords all day every day? Maybe less talented musicians is actually what makes certain genres of music. Would a pianist as skilled as Tatom ever make a new age CD?
