Elizium's mainly EBM and industrial, with a slap of futurepop. I'm away from home at the moment, but when I get back I'll check out Blaqk Audio when I get home in a week and fling some more informed suggestions your way.
In the meantime, try the setlists on
ELIZIUM | NM4NP and spend a wee while looking through Myspace with some of the names you see. Try Covenant, Apoptygma Berzerk, Icon Of Coil, VNV Nation, Faderheadz, Freezepop, Combichrist, Crisk and (my current favourite) Zombie Girl for a slice of what tends to comprise a 'peak' set for Elizium these days.
Davey Havoc's been pictured many a time in music mags wearing Apoptygma Berzerk t-shirts, so maybe they're the best to start with?
