 Like "Close Encounters of the Third Kind" another Spielberg film he scored, Williams felt he needed to write "pieces that would convey a sense of 'awe' and fascination" given it dealt with the "overwhelming happiness and excitement" that would emerge from seeing live dinosaurs.In turn more suspenseful scenes such as the "Tyrannosaurus" attack required frightening themes.The first soundtrack album was released on May 25, 1993.
