Unplayed By Human Hands is the title of the two album recordings made in the mid-1970s of computerized organ performances recorded at The All Saints Church, in Pasadena, California on their 90-rank Schlicker pipe organ. The project was headed by Prentiss Knowlton, a student of computer science at The University of Utah. The computer that they used to control the pipe organ was a PDP-8 minicomputer manufactured by Digital Equipment Corporation in 1965. Edited by Curtis.
