Cornelius Cardew

Cornelius Cardew (7 May 1936–13 December 1981) was an English avant-garde composer, and founder (with Howard Skempton and Michael Parsons) of the Scratch Orchestra, an experimental performing ensemble. He later rejected the avant-garde in favour of a politically motivated 'people's liberation music'.
His sons Horace Cardew and Walter Cardew are also musicians.
