• Richard Lerman’s “Sections for Screen”

We all know how important the soundtrack is to most films, and scores by certain composers—Ennio Morricone, Toru Takemitsu, Bernard Herrmann, Georges Delerue, and John Barry, to name a few—more than stand on their own. Other soundtracks rely heavily on nonmusical material, such as Walter Murch’s brilliant sound design in the Francis Ford Coppola film The Conversation. Though it’s rare for filmmakers to place as much emphasis on sound as they do on what’s on the screen, a program screening at the Gene Siskel Film Center on Thursday night at 6 PM offers just as much to fans of experimental music and noise as it does to cinephiles.
