Recording Session: Louis Kaufman, Violin, with Chamber Orchestra These private recording sessions (which were not public performances) took place on December 25, 30, and 31, 1947, and the product was a full recording of Vivaldi's "The Four Seasons". Since a recording ban called by the musicians' union was set to take effect on January 1, 1948, the sessions were held at midnight, the only times available in the Hall's fully-booked schedule. It is possible that the sessions were actually 12/26, 12/31, and 1/1/1948 at 12:00 AM, although this seems unlikely, as the final session would have violated the onset of the recording ban. According to the New York Times, the Concert Hall Chamber Orchestra was a pick-up ensemble assembled for these recording sessions (also 12/30, 12/31/1947); the players mostly came from the New York Philharmonic.
