On what would have been Milton Babbitt’s 97th birthday, here’s a gift to all of us from the Digital Archives: the unpublished manuscript to the composer’s Relata II, as marked by Leonard Bernstein (its dedicatee) before he, as our Music Director, conducted it as part of the Philharmonic’s 125th anniversary season. The program preceding it was Bach’s Brandenburg Concerto No. 5 and Prokofiev’s Violin Concerto No. 1 (with Isaac Stern as the soloist). You can page through the entire score here.
