The underside of the orchestra is raised up for "The Ferry Scene." Williams orchestrates power that grows into a mass of terror with chugging brass, pounding percussion all draped with other worldly choir voices from above. It’s a beautiful design of music.

Williams pushes the orchestral throttle down with "Reaching The Country." There is still a sense of impending doom but it’s done more gently with dark brass and strings.

You can literally feel something coming up from below, while the street splits apart during "The Intersection Scene." The voices rising up in note are very frightening.

"Ray and Rachel" give the soundtrack a little rest before being attacking again with dread.

Things get frantic again as we "Escape From The City." Trumpets and horns push us through the stalled cars and people walking aimlessly along the New Jersey Turnpike.

Williams uses the instruments of his orchestra like a long metallic tendril while "Probing The Basement." Orchestral ambience is highlighted with swelling brass and strings. It’s music to make you feel nervous and on the edge. It works like a charm and I loved how the music literally moves around you, searching to get you.

The strings carry you delicately into "Refugee Status." John Williams does a great job of bringing intensity to "The Attack On The Car." What I liked best about this track is how it doesn’t sound like music representing the aliens. In this scene, it’s people who are attacking the car, so Williams uses strings more prominently than brass giving it more of a human feel.

"The Separation Of The Family" is the gentlest piece on the soundtrack. Soft piano traces the emotion of the family getting split up.

Williams puts himself into the shoes of Tom Cruise’s character when he has "The Confrontation With Ogilvy." This is one of the most horrifying scenes in the movie and the horror doesn’t stem from attacking aliens. The building layered orchestra elements take us into the raw violence of the scene.

Though it’s focused on the emotional drama of the family, the threat of alien extermination still drifts over "The Return To Boston."

Williams slowly builds the intensity of "Escape From The Basket." Beginning with a gloomy foundation, the track builds into nine and half minutes of utter terror.

"The Reunion" joins the music representing separated family members. Morgan Freeman adds narration to help Williams wrap the film up with "Epilogue."

The foldout booklet Decca Records has put together, features nice stills with text and quotes right from the movie. Steven Spielberg essays his thoughts on what John Williams created saying, "John reached for something not of this earth and composed a score that you feel on your skin, even before you become aware that you are actually hearing it."
