Whilst I'd not call rammstein an/the antichrist.
Till lindemann is one sick fucking puppy. Just look at the lyrics to songs like 'sehnsucht' (talks about him doing some pretty twisted things with his sister. For ex 'finger slips down to mexico' is one line in that song, translated into english). And 'mann gegen mann', I'm not even GOING there!.
And for one of his songs, I forget which, he was meant to do this stage effect with a light photoshopped or something, into his mouth, I forget the song now,it was for the video.
Rather than do that though, I read that Till had a slit cut into the side of his cheek, to feed the light through so whenever he opened his mouth to sing, you see this superbright white glow in his mouth.
