Imagine the master Tfers from this shite and endless ability to tweek digitally into something meaningful for output.
Also broken stuff reconstruction interesting. Do anybody have Ho’s 8th sonata shards? Hmmmm.
Horowitz broke the acetate discs to another 1945 concert where he did the NYC premiere of the Prok 8. He played it from the score so it might have been a sightrape that he deliberately destroyed
At any rate, they concert does not exists anymore.
