German industrial Metal/EBM band, formed in 1980 by Jürgen Engler and Bernward Malaka in Düsseldorf.

The band has had a diverse range of musical influences over time, including the percussive industrial Stahlwerksynfonie (1981) than to a more synth-pop styled Volle Kraft voraus! (1982) and Entering the Arena (1985), with the latter album featuring their first English-language material. The band later established itself as an industrial metal band, releasing four albums predominantly in this genre, from 1992 to 1997 with each labelled 1 to 4. The band has released additional albums since 1997, including the predominantly electro-industrial Als wären wir für immer (2010) and The Machinists of Joy (2013), before revisiting the metal sound they had pursued in the 90s with V.
