In 1987 Henrik Nordvargr Björkk, Jouni Ulvtharm Ollila, and Leif Holm forged a band that would be an outlet for blasphemous prophecies, yet from a unique sonic spectrum. The unholy triumvirate were already hitting hard as Pouppée Fabrikk, with Maschinenzimmer 412 unleashing their deepest, darkest personas. Jonas Drakhon Aneheim joined in 1995, replacing Holm and thus enacting the change of name to the abridged MZ. 412.

Maschinenzimmer 412 are the inventors of black industrial, a dark and haunting music which mixes industrial noise, ritual ambient and black metal atmospheres. The project came back in 1995 with the shortened moniker Mz.412 and a typical black metal look (painted faces, long hair, black leather), which was later abandoned.
