Dr. John Chowning (b. 1934) is a pioneering computer musician, composer and professor who, in 1967, discovered the FM synthesis algorithm. This breakthrough in electronic music allowed for  simple, yet rich timbres described as sounding "real." With this discovery, Chowning composed singular, dramatic electronic music and changed the timbre of music forever.

Chowning utilized the potential of computers to synthesize sounds according to programmed instructions. The composer's use of his own FM algorithms, digital synthesis with computers and the new compositional concepts offered by a programmable musical structure combine to create some of the most original and unique electronic music ever created. The compositions on this LP were realized between 1966 and 1981 and the music on this LP, with the exception of Stria, was originally released on CD in Germany (Wergo, 1988). The version of Stria included here contains a section not included on the Wergo CD. Thus, this version of Stria is complete. This is the first time these purely digital recordings have been released on an analog medium. The original dynamics of these groundbreaking compositions have been preserved on this LP. As a result, listeners are advised to increase volume with caution.

In 1975, John Chowning founded the CCRMA - Center For Computer Research In Music and Acoustics at Stanford University. Through Stanford, Chowning licensed his groundbreaking algorithms to Yamaha resulting in numerous new instruments including the iconic DX series of keyboards. In 1972, his composition Tureens which is included on this LP, was the first to create the illusion of continuous 360-degree space using four speakers.
