I don't know if I should post it.
Psychic Tv - infamous First transmission vhs.
Released in limited amount. It mimicked the religious sects and brainwashing. Or maybe they really were that fucked up. nobody knows. it's only an excerpt. The full video is 4 hours length. If you're lucky, you may find it.
You have to google it. There is a vid on yt, but I don't think I can post it without being banned.
