Invocation of My Demon Brother - Kenneth Anger (1969)

Here is a very trippy film by Kenneth Anger. It features scenes which appear that they have been filmed through a kaleidoscope, mirror images and satanic rituals amongst other strange happenings. Around the 4:30 mark is when things all start to get a bit mashed up. Mick Jagger also composed the soundtrack in which he is playing a Moog Synthesiser which is extremely annoying so you may want to mute it.
