However, in my world Jerry Goldsmith is the master. His ability to create atmosphere and tension is unmatched. You can feel it. You become part of the film. Also, his work is typically darker than Williams - which I prefer. Williams is really more of a reoccurring theme \ fanfare guy with an occasional atmospheric piece with some tension or suspense. Goldsmith, on the other hand, seems to inhabit that world. These are examples of what I'm talking about;
Alien - Main Title
Logan's Run - The Monument
Patton - The Battleground
