Yeah, George was (is) not so amazing by what he plays but how he plays it. All those quintuplets, sextuplets, and 7 over 1 (whatever that is called) note groupings is hip and very hard to do and make sound good. Plus he is the god of octaves, I never heard someone play octaves so clean and fast. Plus he adds that extra note to the octave, I believe it's the 4th (?).
Not to mention he plays with so much soul.
