Apparently, I'm on a mission to start a thread for every subgenre of music in existence. But this subgenre is the best. Really the best. There's room for a little new wave in here if it kind of straddles the border, but mostly you should be keeping it angular, keeping it weird, keeping it atmospheric, keeping it too smart for its own good. Here's a bunch of less recognized tracks (than your Joy Divisions and your PiLs and your Gang o' Fours) that are fantastic.
Fatal Microbes - "Violence Grows".
Homosexuals - "Astral Glamour".
The Prats - "Disco Pope".
Flying Lizards - "Sex Machine".
The Astronauts - "Books" (the beginning of this one is clipped off for some reason, I think most copies of this album on the internet are ripped from vinyl and the tracks aren't quite cut at the right spots).
