While we're on the topic of really early works of well-known bands, here's 1974-76 by Cabaret Voltaire. This one is official and was released in 1980 and it consists mainly of the bands rawer, more experimental, and unrefined stuff. If you're looking for another Red Mecca or Micro-Phonies you're not going to find it here. Not to say that's a bad thing though, this album is excellent, just nowhere near as accessible as something like Red Mecca. It's a very peculiar album, definitely worth a listen, especially if you're a big fan of early industrial acts like Cabaret Voltaire or especially Throbbing Gristle.
