Jurassic Park is the twelfth project on which renowned composer John Williams worked with Steven Spielberg. He composed, conducted (with Artie Kane) and produced the film's score. John Neufeld orchestrated most of the cues, with Alexander Courage entirely orchestrating three and Conrad Pope partially orchestrating two others. MCA Records released a soundtrack album for the film on May 20, 1993. Also produced by Williams, this album includes most of the film's major cues, sometimes edited together into longer tracks and often containing material that was unused in the film. Several passages are also repeated in different tracks.
