I have a confession to make; I love film soundtracks. I like the film music of John Williams more than any other, and that's not easily said with the likes of Horner, Zimmerman, and a miriad of others. But Williams... Star Wars had me hooked as did Fiddler on the Roof, Jaws, Schindlers List, Superman the Movie, even his TV stuff like Lost in Space (credited as Johnny Williams).
So Jurassic Park... the dinosaurs were so realistic in the film butwould it have been as good without the music? try watching the film with no sound... it doesn't work.
To my mind, the mark of a good soundtrack album is one you can listen to and appreciate without having seen the film and Williams' scores do just that, Jurassic Park being no exception. The music is a character in itself, and I think he does this by composing themes and not music to a scene. The themes are then used to accompany appropriately timed scenes in the film thus enhancing the mood of the scene. However, the album returns to the themes and as such work brilliantly.
Jurassic Park is an album which I return to regularly, the music is simply terrific, uplifting, exciting, relaxing, even comical at times. This is Williams at his best, get it.
