Die Krupps (German pronunciation: [diː ˈkʁʊps]) is a German industrial rock/EBM band, formed in 1980 by Jürgen Engler and Bernward Malaka in Düsseldorf. Their initial sound throughout the 1980s combined synthesizers with metallic percussion. Die Krupps were key in the Europe wide progression of Electronic Body Music culminating with the collaboration in 1989 with British band Nitzer Ebb on a re-release of Wahrer Lohn/Wahre Arbeit. In 1992, they began to utilize guitars and more sounds derived from heavy metal music, with the release of their album I (as in the number One). It was a pioneering move which led to a number of other bands using the electronic/metal combo as a template in keeping with a deeper industrial sound.
