The Concerto for Prepared Piano and Orchestra is one of Cage's most delicate works. The orchestra is treated as a group of soloists throughout, and for the most part operate with a small set of pitches and timbres, but is extended by a large array of percussion instruments played by four players. The piano, played by the superb contemporary piano interpreter Stephen Drury, weaves between the orchestral sonorities, rarely taking extended solos, as the piece becomes progressively more sparse until it tapers into silence at the end.
