The Reverend Walter Hussey reimagined the church as a place of living artistic creation, commissioning work from major figures in both music and visual art, including Benjamin Britten, Leonard Bernstein, Marc Chagall, and Henry Moore. Early in his career, he commissioned Britten’s Rejoice in the Lamb; toward its close, Bernstein’s Chichester Psalms. Framed by those two landmark works, the Back Bay Chorale opens its season with the world premiere of Zachary Wadsworth’s De Profundis, a setting of texts by an imprisoned Oscar Wilde composed as a modern analogue to Rejoice in the Lamb.
