Ancient Voices of Children is one of the seminal vocal works of the 20th century, not just for the huge demands it makes on the singer's vocal technique, but also in the way that all of its avant-garde sound effects really do reflect the most sensitive response to Garcia Lorca's poetry. Soprano Barbara Ann Martin really has the measure of the piece. She proves herself a worthy successor to Jan DeGaetani in the premier recording of the work. Her performance is thrilling, and the instrumental accompaniment, recorded in the presence of the composer, is perfect. The same holds true for the other works on the disc, particularly Crumb's haunting Dream Sequence, music of hypnotic power. In sum, a magnificent tribute to one of our greatest living composers.
