Michael Tippett
Sir Michael Kemp Tippett, O.M. (2 January 1905 – 8 January 1998) was one of the foremost English composers of the 20th century. Tippett was regarded by many as an outsider in British music, a view that may have been related to his early conscientious objection and his homosexuality. His pacifist beliefs led to a prison sentence in World War II, and for many years his music was considered ungratefully written for voices and instruments, and therefore difficult to perform.
