Oomph! is a German rock band from Wolfsburg, formed in 1989. The band pioneered the Neue Deutsche Härte movement. Their work contains lyrics in both English and German, with a shift towards German exclusively on recent albums (GlaubeLiebeTod, Monster, Des Wahnsinns fette Beute, XXV, and Ritual are entirely in German).
