<p>Steven Spielberg had long wanted to do an alien invasion movie featuring very bad visitors to Earth, and he finally checked that off his list with "War of the Worlds." In telling the story, John Williams went into full horror mode, employing some of the tactics used previously by such classical composers as Igor Stravinsky, especially in the first alien attack that turned out to be one of the most violent nonfiction moments Spielberg has put on film. Host Jeff Commings is joined by composer/conductor Eduardo Victoria as the two detail the high points of the score and how the music really has similarities to Williams' previous work, including Jaws and Superman. </p>
