"Entered from New York Times review.\r\nAccording to review, this program was presented by John Cage; review notes that although Cage didn't appear as part of the program, \"it was a one-man show nevertheless. As well as inventing the form, he managed the event, composed all the music, and prepared the five pianos so it was possible to play his compositions.\"\r\n\"Prepared Pianos Give Odd Program.\" New York Times (1923-Current file) Dec 11 1946: 40.
