What's the most extreme, intense, hard hitting, tear your face off, piss blood, exotic, fast, mindblowing, frightening, hardcore, electronic in the house/industrial/electronic genre?

any noise artist probably. Stuff like:
Merzbow
Massona
Whitehouse
Marax
Yamaakago
Aube
but it's probably closer to experimental than electronic.

aube's stuff isn't all that hard, ya know? just check out the millennium series...

I'd say Xanopticon's stuff is pretty hard.

not really noise, but beat oriented, I mean.

Hard house, industrial dance type stuff

Yeah yer right about Aube.

I don't know... Enduser maybe? http://www.sonicterror.net/enduser/site/enduser.html

I don't like the vocals, looking for darker, and heavier.

Using my lifeline and im'ing.

So far Wumpscut and Atari teenage riot are in the lead from my friend's suggestions.

Well, it's not Industrial by any means, but Venetian Snares fits the bill for most everything else...

...although as far as Industrial goes I'd say dumb the Wumpscut and go find yourself some Numb, particularly the album "Blood Maridian"...I think that will be satisfied with that release.

That's a great CD but I still think ATR might be the most insanely intense thing I've ever heard.

Numb is definitely much better though.

Just trying to find the most extreme.
