On October 11, 1963, the Foundation for Contemporary Performance Arts held its first publicly sponsored event. The performance, “Music of Orchestra and Chorus by Morton Feldman and Earle Brown,” was conceived of by Foundation co-founder John Cage as an opportunity for Feldman and Brown to present four works for a large ensemble. This is a scarce documentation for the event and has a contemporaneous pencil note “Wxxxx (unreadable) at slow tempi and with long rests & durations” in an unknown hand.
