Unplayed by Human Hands

"Unplayed By Human Hands" are the titles of two album recordings made in the mid-1970s of computerized organ performances recorded at the All Saints Church in Pasadena, California on their 82-rank Schlicker pipe organ.

The project was headed by Prentiss Knowlton, a student of computer science at the University of Utah.

The computer employed for the task of controlling the pipe organ was a PDP-8 minicomputer manufactured by Digital Equipment Corporation (DEC) in 1965.
