Scored for chorus, children’s choir, organ and chamber orchestra, St Luke Passion adopts a pared-back focus on choral voices over its 75-minute span. Seeking a more spiritual, inward approach to match Luke’s text, the composer eschews settings of interpolated texts as arias and the customary Evangelist and Christ soli: everything is sung by choral forces. A children’s choir grants a measure of innocence to Christ as the sacrificial lamb, emphasising aspects of otherness, sanctity and mystery.
