When we think of film noir, we tend to think of a mood best set by a look: shadow and light (mostly shadow), grim but visually rich weather, near-depopulated urban streets. You'll see plenty of that pulled off at the height of the craft in the movies that make up "noirchaeologist" Eddie Muller's list of 25 noir pictures that will endure, which we featured last week. But what will you hear? Though no one compositional style dominated the soundtracks of films noirs, you'll certainly hear more than a few solid pieces of crime jazz. Xeni Jardin at Boing Boing, writing about Rhino's eponymous compilation album, defines this musical genre as "jazzy theme music from 1950s TV shows and movies in which very bad people do very bad things." She links to PopCult's collection of classic crime jazz soundtrack album covers, from The Third Man to Charade (the best Hitchcock film, of course, that Hitchcock never made), to The Man With the Golden Arm, all as evocative as the music itself.
