It is perhaps no coincidence that Wendy Carlos's synthetic soundscapes for TRON are at least as memorable as Vangelis's score for the real-world companion to TRON: the movie BLADERUNNER. Though neither film and neither composer's work was intended to be a companion to the other, due to subject matter, production, the year of release, and other factors, it is almost inescapable that TRON and BLADERUNNER act as the two sides of a single cyber coin.
Both albums even suffered delayed release troubles, in that Vangelis's score for the Ridley Scott film was not available in any form prior to 1994, and Carlos's score for TRON was not available on compact disc until 2002. Both scores are remarkable feats, dating to an era when electronic music was still very much in the toddler phase, and it took supreme talent to wring soaring sounds out of clunky analong equipment without digital recording processes.
The TRON soundtrack is especially precious in that it was thought to have been lost for good when Carlos discovered that her master library tapes upon which TRON had been recorded were rapidly eroding. Thanks to Disney, however, the tapes were restored in a one-time, one-shot process for one final remastering onto digital media, and thus Wendy Carlos's best known film score shines and sparkles like the day it was first laid down onto tape.
If you have seen the movie, or if you love it in the way I love it, then buying the Carlos score is a no-brainer. But even if you disliked the motion picture or otherwise found TRON to be a forgettable viewing experience, the soundtrack is still a tremendous piece of electronica, and I highly recommend it to any self-respecting electronic music fan, young or old.
