Soundtrack help: Graz'zt

I like employing music around my table during sessions, and I particularly like it when a theme hits just right.

Recently the warlock character managed to get herself tangled up with Graz'zt (not her patron), and I need a theme that fits.

Here's what I'm thinking:

- Excessively sultry, to the point of being wrong or... Icky?

- An underlying menace that looms over the entire track.

- Instrumentation isn't very important. I don't care if all the instruments are modern, if it's all synth and/or distortion, or if it has a sax solo.

Thanks in advance.
