Just some southern gothic. I've been thinking of how to bring this kind of atmosphere into a tabletop experience.
Searching for the wrong-eyed Jesus
Possible other stuff: 16 horsepower, Tom Waits, Reverend Glasseye. Justified, Carnivale. 90's series like Twin Peaks or American Gothic. Maybe some witch house.
Oh, and Confederate nostalgia/revisionism/restoration/teaparty. The best kind of horror really.
