That intense looking dude in the middle is Wiedergaenger, the sole human being behind Total Negation's intense atmospheric black metal. I have no idea who the people in the creepy white masks are. Possibly the specters that he conjures with his music? You won't get any answers from the video for "Kronzeuge" (other than the answer to the question "how do you make a video out of eight minutes of photographs and creepy Blair Witch Project outtakes?"), but it captures the mood pretty effectively. Check it out for yourself below!
