I think that there is two things relevant to this video.
#1 It is from August 2002. Jason did this a DECADE ago. As great as this is, JR now has ten full years behind him to have improved. I would suspect that his practice habits are a bit better than yours and I know better than mine. Hell, I'd hope to do what he did a decade ago in a few years----and that is only copying it--not creating it.
#2 There was a LP in this video that was played at the same level that JR's harp was.
