The "Cogito Ergo Sum" sounds like a bizarre black metal mixed with ebm/techno. Mindblowing and intensely chaotic. All in all each album actually is a "bad trip". Frightening and obsure, taking off all grounds that one can safely lean. Such they are, bad trips...
This is amazing stuff. Does anyone have a link to the album Überlebenskunst? A rip of Trauma in higher quality than the 128 kbps transcode available from last.fm would be nice as well. A link to somewhere I'd be able to buy the albums would really be even better; this stuff is so obscure I'd be amazed if it's even still in print.
The albums are quite cheap in Germany...f.e. via Amazon:
