On this week's Film Music Friday we're hearing music from the films of Alfred Hitchock. Over a career that stretched from the silents to the '70s, the Merchant of Menace worked with some of filmdom's top composers, including Miklos Rozsa, Bernard Herrmann, Dimitri Tiomkin and John Williams. We'll hear music from such films as Rebecca, Spellbound, Strangers On a Train, North by Northwest, Pyscho and others.
