His Il Giuoco (1966) was the first large-scale work for Moog synthesizer. With his Nonesuch LP Tragoedia, working as music assistant to Alwin Nikolais, and inclusion in the sound-track of Fellini Satyricon, he received early recognition primarily in the field of electronic music. Scores for many dance companies followed, including The Pennsylvania Ballet, as well as incidental music for theatre, and television. His opera, The Innocent, was produced in Philadelphia by Tito Capobianco. Recent concertos for violin, viola, and piano, along with numerous chamber music commissions, have brought him renewed recognition. Purewater, a chamber opera, written in collaboration with librettist Ann McCutchan, will be presented by The Center for Contemporary Opera in fall 2018. He taught at The Juilliard School and University of the Arts. His teachers included George Rochberg, Karlheinz Stockhausen, Ralph Shapey, and Kent Kennan.
