gloomy music?

I'm finally about to start work on 'Drowning City'; I have a piece of paper taped to the drawing board with my page sizes ruled out on them, I have pencils, I have a working Wacom tablet again, I have a scanner, I have some thumbnails of two test pages (to work the initial bugs out of my planned methodology)...

After ruling out said page sizes, I determined one final lack: Music.

( Help me pick some. )
