For those of you unfamiliar with Les Liaisons Dangereuses, it contains hummable melodies, rip-roaring action cues, "beautiful" love themes, tons o' syrupy strings, some woodwinds, and "kick-ass" action brass, all played by the London Symphony Orchestra.
I'm unfamiliar with both the music in this movie and the movie itself, but I listened to a few clips of Thelonious Monk's music ( https://www.youtube.com/watch?v=F-7rkYUEcWI ) and it sure sounds worthwile.
I absolutely idolize Monk--both as a pianist and as a composer. I never go very long without sliding a Monk CD into the player. One incredible composition after the other.
