An all-too-rare new recording from Polyphony and Stephen Layton presents highlights from the choral repertoire by four twentieth-century American giants: Samuel Barber, Leonard Bernstein, Aaron Copland and Randall Thompson. Framed by Thompson’s understated favourites Alleluia and Fare Well, the programme includes Bernstein’s Missa brevis, Copland’s early set of four motets, and—of course—Barber’s inimitable Agnus Dei.
