Koyaanisqatsi (life out of balance in the Hopi language) is primarily a score by Philip Glass as well as the movie supporting it. The movie is a sequence of slow-motion and timelapses of United States citie, sung in the language of those who had to disappear for this to take place.
Since A brief history of time was not available as a soundtrack by this time, this is the piece which I acquired instead at a time when very little was available on the Internet (I estimate in the late 90s).
