Original sound track by John Williams
This is the fully orchestrated original version, not the predictable disco derivation by Meco. Williams has also scored (certainly the right verb, financially) Jaws and Star Wars, among other films, and he’s on target again. The music follows the sequence of the film, so it correlates with the moods of sighting UFOs, their physical evidence (we can almost feel a cosmic Electrolux sucking Barry away) and, ultimately, contact with those space cadets from Out There. We may not be alone, but as a master of the film sound track, Williams is.
