(Born; London, 5 Sept 1920; Died; Los Angeles, 1 Feb 1990). English composer. He studied with Morris at the RCM (1937-41) and after the war with Seiber; he then taught in London before moving to Santa Barbara in 1964. He was the most prominent British composer to emerge after World War II, his free atonal style having much impact after a period when British music had been dominated by the pastoral folksong tradition. His early works were influenced by Bartók, Hindemith and Schoenberg and consisted mostly of orchestral and chamber pieces, notably the first three symphonies (1949, 1951, 1960) and concertos. Later works, in a fluent contrapuntal style, are more economical and concentrated; they include choral music and songs.(c)Groves Dictionaries, MacMillan Publishers Limited, UK
