When I was taking lessons last year, I introduced my teacher to the "Second Winter" album by Johnny Winter. It was kinda fun watching his eyes get all big! It was kinda discouraging to see him try to duplicate a couple of the riffs in "Memory Pain", and collapse in a heap. We kept at it though.
The point is, the players you look up to are not setting up roadblocks... they're setting up goalposts. If there's some song you wanna play, or some technique you wanna learn, you can get it, if you work at it.
Me, I take great comfort in the sure knowledge that on a good day, I'm almost as fast as David Gilmour.
