AGP90 is the third of four featuring works by the British composer Harrison Birtwistle. Born in 1934, he came of age with Peter Maxwell Davies and Alexander Goehr, and like them studied in Manchester. Birtwistle's music belongs to no clearly identifiable school. It is characterized by a fine ear for both harmony and orchestration, and some rather unusual approaches to musical structure. AGP90 includes three works composed between 1993 and 1995.
