Here is one of the great contemporary masterpieces for voice. Three Voices was composed for Joan La Barbara, a singer and performer of avant-garde music in the tradition of Cathy Berberian or Jan DeGaetani. In live performance, the singer stands next to two loudspeakers that play two prerecorded tapes of her voice, to which she synchronizes herself. At the center of the work is a setting of the poem Wind by Frank O'Hara. The various vocal patterns on either side of the poem were inspired, as in all Feldman's late music, by the patterns on Oriental carpets, and you actually can hear the slow modification of shape and form as the music proceeds. It's a remarkable work, and La Barbara's performance is definitive. --David Hurwitz
