Secret Music follows Pulitzer prize winning American composer David Del Tredici "b. 1937" through his transformative and uninhibited commitment to writing what he calls "gay music," a repertoire that celebrates the joys and honors the struggles of his life as a gay man. In his music, Del Tredici courageously and provocatively embraces his sexuality while confronting the fears and concerns shared by gay people of his generation--those of violence, marginalization, loneliness, and the need to be heard above the din of the normative. The film explores the urgent questions that emerge where biography, social history, and music intersect.
