I just realized we don't have a thread for this guy.
He's an Australian musician, combined elements of industrial, post-punk and neo-classical into a behemoth of a songwriting style. Dark brooding vocals and some rather strange lyrical themes are present throughout his work. He emerged through the 'no-wave' era but his music really doesn't belong to it, there's a vast electronic influence to it. He's done quite a few collaborations over the years (including ones with Lydia Lunch and Nick Cave!) but these works really stick out as something special to me:
1985 - Nail (Scraping Foetus off the Wheel)
1988 - Thaw (Foetus Interruptus)
1995 - Gash (Foetus)
2001 - Flow (Foetus)
I know there's other fans here. Let me know if anyone needs an up, I've got most (?) of his work.
