This major work by one of Britain's leading choral composers was commissioned by St Mary's Cathedral, Edinburgh. The setting is terse and direct, in the manner of the Poulenc Mass, and the textures often unusually pared-down. By turns fiery and exuberant, and inward and numinous, the music includes a huge variety of textures and techniques, including flowing melismas, luminous key changes, and pure homophony. This is a work of great power that will appeal to committed concert and church choirs.
