Looker

I just watched the above named Michael Crichton film from 1981. Its pretty cheesy but as expected from the title it looks amazing, with beautiful 80's set design and a ton of early computer generated stuff. The music is by Barry Devorzon and is completely sequenced-synth based, but it doesn't seem to have been released as an OST, and is therefore not online either. Below are some clips, as well as the 1982 showreel of the company who did the CGI stuff
