Morton Subotnick is one of the pioneers in the development of electronic music and an innovator in works involving instruments and other media, including interactive computer music systems. Most of his music calls for a computer part, or live electronic processing; his oeuvre utilizes many of the important technological breakthroughs in the history of the genre.

The work which brought Subotnick celebrity was Silver Apples of the Moon. Written in 1967 using the Buchla modular synthesizer (an electronic instrument built by Donald Buchla utilizing suggestions from Subotnick and Ramon Sender), this work contains synthesized tone colors, striking for its day, and a control over pitch that many other contemporary electronic composers had relinquished. There is a rich counterpoint of gestures, in marked contrast to the simple surfaces of much contemporary electronic music. There are sections marked by very clear pulses, another unusual trait for its time; Silver Apples of the Moon was commissioned by Nonesuch Records, marking the first time an original large-scale composition had been created specifically for the disc medium - a conscious acknowledgment that the home stereo system constituted a present-day form of chamber music. Subotnick wrote this piece (and subsequent record company commissions) in two parts to correspond to the two sides of an LP. The exciting, exotic timbres and the dance inspiring rhythms caught the ear of the public -- the record was an American bestseller in the classical music category, an extremely unusual occurrence for any contemporary concert music at the time. It has been re-released on Wergo cd with The Wild Bull.

The next eight years saw the production of several more important compositions for LP, realized on the Buchla synthesizer: The Wild Bull, Touch, Sidewinder and Four Butterflies . All of these pieces are marked by sophisticated timbres, contrapuntal rich textures, and sections of continuous pulse suggesting dance. In fact, Silver Apples of the Moon was used as dance music by several companies including the Stuttgart Ballet and Ballet Rambert and The Wild Bull, A Sky of Cloudless Sulfur and The Key to Songs, have been choreographed by leading dance companies throughout the world.
