And so Graham Ross and the Choir of Clare College, Cambridge, reach the end of their musical pilgrimage through the church year. What began back in 2013 with ‘Music for Advent’ now reaches its conclusion five years and nine discs later with a celebration of Trinity Sunday – the final feast day of the liturgical calendar. What a triumphant finish it is. The same breadth of repertoire, the thoughtful, creative programming, the consistent, quality performances that have characterised every volume in the series continue here in a collection that pairs works from the English choral tradition (Byrd and Stainer, Britten and Gabriel Jackson) with those from Russia (Tchaikovsky, Grechaninov, Chesnokov, Glinka).

The full-throated directness and declamatory warmth that swells so instinctively through Stainer’s I saw the Lord, Wood’s Hail, gladdening light and Britten’s Festival Te Deum, bursting out most jubilantly in Stanford’s setting of Psalm 150, also works beautifully for the Russian music. The opening Cherubic Hymn by Grechaninov (five different Cherubic Hymns introduce the album’s five sections, each of which offers a different perspective on the Trinity) shows off the choir’s fine low basses, while Glinka’s spreads out its choral blend like a fine-woven cloth.

As usual there is also a smattering of new works. The Sanctus and Benedictus from James MacMillan’s Mass offer no peaceful blessing but one curiously troubled by desperation and doubt, balancing the contemplative sweetness of Joshua Pacey’s Tres sunt. Most interesting though is Ross’s own Duo Seraphim, whose two duelling soprano voices conjure beings of dazzling strangeness – the alien creatures of a medieval illumination rather than rosy-cheeked Victorian angels.

This really is exceptional singing – immaculately balanced and blended, with text always at its heart. Ross and his young singers have given us quite the gift in this series. I can’t wait to hear what they do next.
