AC/DC, Brings formed in 1991 with Harry Alfter, Christian Blüm, Matthias Gottschalk (who would eventually be replaced by Kai Engel), and brothers Paul and Stephan Brings. The group's first album, 1991's Zwei Zoote Minsche, shot to number three on the German charts, and the band's presence on the German Top 40 charts essentially continued over the course of the next 15 years. The band stirred up some controversy in 2006 with the single "Hay! Hay! Hay!"; the song's alleged pro-drug stance had Brings banned from the Cologne Karneval that year. The single's eponymous album hit stores in 2007.
