On Oct. 26 nine year old Ethan Bortnick played “Arctic Jazz” “by me” on ABC Good Morning America.
He discussed his piece “Time Machine” which he said deals with the journey of a Florida manatee.
He had appeared before in March.
The jazz did sound as though it was being improvised; it was a lot less formal than Gershwin (or even Alban Berg).
