DVD QUESTION, HELP!!

This is a question that's been nagging me to no end for a LONG time. On the White Heat DVD, there is, obviously, a featurette called "Top of the World: White Heat", and during that featurette there is a piece of very ominous-Bernard Hermanesque music that is played OVER AND OVER AND OVER AGAIN, and is played over the end credits. I'm afraid that, after watching the featurette, I have grown obsessed with this particular piece of music and am DYING to know what it's called.

I'm guessing that it's a piece of music composed for a different movie (just like the way the documentaries on the Hitchcock DVDs use music from all SORTS of different Hitchcock films). Does ANYONE know what this piece of music is called? Honestly, this thing is driving me INSANE.
