Sunday Synth Jam: In this vintage electronic music performance from 1977, electronic music pioneer Laurie Spiegel performs Improvisation on a ‘Concerto Generator’.
Spiegel plays the Bell Labs Digital Synthesizer, an experimental additive synthesizer designed by Harold G. Alles and Douglas Bayer at Bell Labs in 1977-78.
Here’s how Spiegel summarizes Improvisation On A Concerto Generator:
This composition was commissioned by Bell Labs and the Motion Picture Academy for the 50th anniversary of talking pictures.
Working with the Alles synthesizer, with its extensive array of input and output channels for control, was a real pleasure after years of GROOVE’s extreme restrictions.
The interactive software I wrote for this composition recycles the player’s keyboard input into an ongoing accompaniment. However, writing the software from a remote DEC PDP-11 computer (see also the PDP-11 FAQ and PDP Music Survey) in the new ‘C’ computer language still undergoing frequent change, within a still-experimental UNIX operating system, without the control inputs or sonic output, under a tight deadline, while the Alles synthesizer hardware was still under construction, turned out to be quite an adventure.
Love this! Also her recent reissue of The Expanding Universe was a huge revelation for me.
Dude, what a dream of woman! Wish she would be into analog though heh
Yes, she is one amazing “composer and general purpose thinker” (her twitter profile – https://twitter.com/LaurieSpiegel ).
Also, here’s a write up on the Alles synth seen in this video, on Wikipedia … http://en.wikipedia.org/wiki/Bell_Labs_Digital_Synthesizer
This thing has a beautiful sound, so musical.
It’s extraordinary how far the technology has advanced in the decades since this performance. Her algorithmic musical composition software Music Mouse was pretty nifty when the Amiga and the Atari roamed the earth.

Awesome moment of music, thank you!
Yes, this has been a favourite of mine for a long time. So inspiring! As is all that she does. Thanks for posting! I love that people are discovering what they’ve been missing lately and discovering her music. She is brilliant.
