I also noticed how he kind of "zones" into the composition that he's playing as if there's some kind of transformation going on as Craig said. It's almost a bit eerie.
He does make a few mistakes but continues playing as if it never happened. As soon as I make a mistake I am compelled to stop playing and replay that part correctly before proceeding with the rest of the song, which makes the mistake even more noticeable to anyone listening. I am also compelled to shout expletives whenever I hit a wrong note. I don't mean to, it just happens.
