The Wrong Side of Midnight

The discography of U.D.O., a German heavy metal band, consists of 19 studio albums, six live albums, three compilations, 17 singles, six video albums and 19 music videos. Formed in 1987 by eponymous vocalist Udo Dirkschneider following his departure from Accept, the group originally included guitarists Mathias Dieth and Peter Szigeti, bassist Frank Rittel and drummer Thomas Franke. Shortly after the release and promotion of their debut album Animal House, Dirkschneider dismissed all band members except Dieth, and rebuilt the group with guitarist Andy Susemihl, bassist Thomas Smuszynski, and future Accept drummer Stefan Schwarzmann. Mean Machine, released in 1989, reached number 31 on the German Albums Chart. Susemihl was subsequently replaced by Wolla Böhm.
