Originally Jerry Goldsmith crafted a very interesting orchestral score that used some synthesizer elements to it. It is a score that is dense with themes that each interweave and interact with each other in surprising ways. It may be one of Goldsmith's most complex scores, and is one that you appreciate more and more each time you listen to it. This may be the reason why Goldsmith was so disappointed when his score was thrown out after the movie was heavily re-edited. This caused Goldsmith's score to be unusable, and also gave the producers a chance to pull in popular electronic group Tangerine Dream to score the film.
Tangerine Dream has simpler more obvious themes but they are catchy and work really well in the shorter cut of the film. This is version I grew up with, so I actually enjoy this version of the score quite a bit. Still Goldsmith is my favorite film composer and what he crafted for this movie was really impressive.
So I figure I'll give you two pieces for the same scene and you can enjoy them. First up is Goldsmith's score for the Dress Waltz, a creepy scene where Mia Sara dances with a dark dress that absorbs her.
And then the Tangerine Dream version of the same scene called The Dance in this case. Enjoy!
