American-born, John Cage, was one of the most adventurous musicians of the 20^th century. Always seeking new musical sounds, he was a pioneer in the technique known as the ‘Prepared Piano’. This involved placing screws, bolts, and pieces of rubber and plastic on defined strings in the body of a grand piano. The fascinating range of sonorities created, often akin to music of the Orient, is explored in the Sonatas and Interludes composed between 1946-8.
