Ambient industrial is a hybrid genre of ambient and industrial music; the term industrial being used in the original experimental sense, rather than in the sense of industrial metal or EBM. Ambient industrial makes use of http://music.hyperreal.org/epsilon/info/industrial_principles.html Industrial principles such as use of anti-music, extra-musical elements and shock tactics, but wields these elements with more subtlety. Additionally, ambient industrial often has strong occultist tendencies, with a particular leaning toward Chaos Magick (the image of the Black Sun is one that comes up repeatedly in post-Industrial music), often giving the music a highly ritualistic flavor.
