I can't believe this! Electro Graphics contains a track - Physic Thunder - that is used in a '84 Commodore 64 promo video when they show us the MOS plant (German).
Timestamp sharing does not work, it is at 8:44.
This video was one of the first times I had early contact with the space-y, chaotic synth sounds and it's amazing to find gap for gap for gap!
Thanks!
EDIT: Does someone else recognizes any other song there? (You can skim through the video, the tracks are played over a longer duration)
