for SSAATTBB unaccompanied. Advent Antiphons is an exquisite concert setting of the Great O Antiphons. Chilcott's writing for double choir is masterful; he embroiders a beautifully-textured work in which echoes of plainchant combine with richly expressive harmony. Without doubt, this is some of Chilcott's finest music: subtle yet potent, haunting and uplifting.
