There is one particular "sound" I really love; what I call "baroque jazz melancholy". This is an almost classical tune with a jazz undercurrent or backbeat and with a minor-moded melody to go.
Examples include the "Main Title" from THE EIGER SANCTION or "Main Title" and "Rickard Escapes" from THE LAST RUN. If there's a harpschicord that goes with it, even better.
Do you know what I'm talking about? Any other examples of this?
