Ralph Vaughan Williams’s sublime Mass in G minor reveals the composer’s absorbing interest in using the modal harmonic language and contrapuntal textures of the English late Renaissance to achieve a huge emotional and dynamic range. Undoubtedly the most technically demanding work on this disc is A Vision of Aeroplanes, a virtuosic motet for mixed chorus and organ. Several neglected works also feature here, including The Voice out of the Whirlwind, an anthem for mixed chorus and orchestra or organ, and Valiant-for-truth, one of several works based on Bunyan’s Christian allegory The Pilgrim’s Progress.
