The Flight of the Bumblebee and Zorba the Greek are couple very technical pieces that would be interesting to hear executed using MIDI.
I had a friend who was the chair of the music department at a college. Somehow, he had managed to go his entire life without hearing Vince Guaraldi’s rendition of Linus and Lucy. He bought the sheet music but wasn’t playing it correctly. I, who can’t even read music, had to show him. Some things just don’t manifest onto sheet music, and that probably goes double for jazz. He ended up playing the piece in his class, and he said the students just went nuts. It increased his “cool” factor with his students.
