Reading the blurb under the video, is this video actually JR playing or is it by this 15-year-old Julien Hanck? It's almost ambiguous from the statement. I was sort of hoping JR's goatee would dip into the top of the frame, just to confirm it was him.

Like Diki, I doubt Rudess would bother much with arrangers, not his bag at all. In that league of ability, and playing arranger, look no further than Marco Parisi.
