What was the final Marilyn Manson album to feature the member who took a stage name from a serial killer?
The Golden Age of Grotesque:  It was also their final studio album to feature keyboardist Madonna Wayne Gacy and guitarist John 5, who would both acrimoniously quit before the release of the band's next studio album. Madonna Wayne Gacy: Stephen Gregory Bier Jr. (born March 6, 1964, Fort Lauderdale, Florida), formerly known by his stage name Madonna Wayne Gacy and by the nickname Pogo (John Wayne Gacy's clown name), is the former keyboard player for Marilyn Manson, from 1989 to 2007.
