I could be wrong. Perhaps this has been released before.
As I've learned, George Lewis was sponsored at IRCAM in the early '80s. His studies there culminated in a May 1984 sound project with Lewis operating three midi-networked Apple II computers linked to Yamaha DX7's which "interact" with invited guests in a series of performances. These guests were Doug Ewart, Derek Bailey, Steve Lacy and Joëlle Leandre.
It seems this series of performances was broadcast on TV in Europe at the time; until now they've not been released as sound recordings.

I think it’s pretty cool.
