Morton Feldman: Friendship and Mourning in the New York Avant-Garde documents the collaborations and conflicts essential to the history of the post-war avant-garde. It offers a study of composer Morton Feldman's associations and friendships with artists like John Cage, Jackson Pollock, Philip Guston, Frank O'Hara, Charlotte Moorman, and others. Arguing that friendship and mourning sustained the collective aesthetics of the New York School, Dohoney has written an emotional and intimate revision of New York modernism from the point of view of Feldman's agonistic community.
