“Ideas enter our above-ground culture through the underground. I suppose that is the kind of function that the underground plays, such as it is. That it is where the dreams of our culture can ferment and strange notions can play themselves out unrestricted.

Occulture, you know, that seems to be perhaps the last revolutionary bastion.” — Alan Moore
