Fury in the Slaughterhouse were formed in Hannover, Germany, in 1987 by brothers Kai Uwe Wingenfelder (vocals) and Thorsten Wingenfelder (guitar, vocals). The siblings then added Rainer Schumann (drums), Christof Stein (guitar), and Hannes Schafer (bass). Fury in the Slaughterhouse's self-titled debut LP was released on January 10, 1989; keyboardist Gero Drnek also joined the band that year. In 1996, original bassist Hannes Schäfer was replaced by Christian Decker.
