If you're still having nightmares about Michael Myers, John Carpenter's soundtrack is guaranteed to provoke a few more flashbacks. Instead of an orchestra, Carpenter uses the creepy sounds of old-school synthesizers, building the mood around two main themes. One is the opening title's tension-building piano riff that returns in a minor key during "Loomis and Shape's Car." The other is the chilly, dissonant chords that are heard on "Michael Kills Judith" and "Better Check the Kids,” whose titles alone are not for the fainthearted.
