I don't know if Foetus qualifies. I had "You've got Fetus on Your Breath" since at least 1979 or 80 seems like. They either preceded hardcore or came out at the very same time. So they can't be post-punk. They are certainly not industrial and definitely not goth.
My fave is Laibach. Got to see them twice:
Laibach - Abuse and Confession - YouTube
Laibach - For you blue - YouTube
Fantastic interp of the old George Harrison blues number.
Laibach / Leben Heißt Leben
