The title of quot;The Decaloguequot; has a touch of the grandiose: it means quot;The Ten Commandments.quot; Yet this score composed by Sufjan Stevens for a dance work choreographed by Justin Peck that premiered with the New York City Ballet in May of 2017 is quiet and experimental. Stevens s piano score as played and recorded by Timo Andres sounds like etudes in the Romantic-modernist tradition as if prompted by Debussy. With quot;The Decalogue quot; now released digitally and on vinyl and CD Sufjan is making-gently without ostentation-new departures.
