October 18 street date. This deluxe edition of "The Decalogue" comprises a Stoughton tip-on gatefold jacket, 180-gram vinyl, 40 page songbook, 9x12 art print, and download card. The title of "The Decalogue" has a touch of the grandiose: it means "The Ten Commandments." 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' piano score, as played and recorded by Timo Andres, sounds like etudes in the Romantic-modernist tradition, as if prompted by Debussy. With "The Decalogue," Sufjan is making - gently, without ostentation - new departures.
