Composed for the Reykjavik Cathedral Choir's "Solo Dei Gloria" Festival in 2004, Advent Antiphons is an exquisite concert setting of the Great O Antiphons. Traditionally chanted or sung between 17 and 23 December, the Antiphons comprise seven brief prayers which proceed in sequence, charting events from before Creation through to the birth of Christ. The powerful sentiments conveyed in these texts are brought to the fore in Chilcott's masterful writing for double choir; he embroiders a beautifully textured work in which echoes of plainchant combine with richly expressive harmony. In the third and fifth movements, the composer instructs the individual sopranos and altos in each choir to sing their parts in their own rhythm, to entrancing effect. Without doubt, this is some of Chilcott's finest music to date; subtle yet potent, haunting, and uplifting.
