.

Laurie Spiegel playing improvisation on a "Concerto Generator" with the Bell Labs Digital Synthesizer, better known as the Alles Machine or Alice, an experimental additive synthesizer designed by Harold G. Alles and Douglas Bayer at Bell Labs (NJ) in 1977-78.

Written by Laurie in C language software (created in 1972 by Dennis M. Ritchie), this composition was commissioned by Bell Labs and the Motion Picture Academy for the 50th anniversary of talking pictures.

The instrument is possibly the first realtime digital synthesizer.

(*) The ideas of early electro-acoustic composers exceeded the available technology. The first performance of "Music Of The Spheres" as conceived by Beyer was produced and recorded in 1977 specifically for this album (for example, the violins were replaced for the three electronic instruments specified in her original score).
