Wade Clarke has almost finished the main theme for Kerkerkruip, which will play in the main menu and the rogues gallery. You can download a preview -- or prehear, I guess -- here. (It's a 6 minute, 10Mb .ogg file.) I hope you like it as much as I do.
Wade has also just released a new EP of his Aeriae project, called Nurse 2 Alyssa Type. Check out his website if you have any interest in electronic music!
