when i first heard "Midnight" by Joe Satriani I could hardly believe it was possible to play. I've forgotten the cadenza now but quite honestly it isn't that hard, it was one of the first things I ever played live. It only uses strong fingers and because it crosses strings there isn't the hassle of loosing force with the second tapped note of each arpeggio. The genius was writing something like that!
If I couldn't laugh at myself how could I laugh at someone less ridiculous?
