Composer, born in Aylesbury, Buckinghamshire, SC England, UK. Strongly influenced by Wagner's principles of music drama, and also by Socialist ideas, his aim was to develop an English style, with a strong choral element, his subjects based on British legend, and he founded the Glastonbury Festival (1914--26). His works include the opera The Immortal Hour (1913), a choral drama Bethlehem (1915), The Queen of Cornwall (1924), five music dramas (1908--45) intended to form an Arthurian cycle (never performed complete), and other stage, choral, and instrumental works.
