They include correspondence with Peter Yates, David Tudor, and Pierre Boulez, among many others. Readers will enjoy Cage's commentary about the people and events of a transformative time in the arts, as well as his meditations on the very nature of art. This volume presents an extraordinary portrait of a complex, brilliant man who challenged and changed the artistic currents of the twentieth century.
