Marilyn Manson didn't invent shock rock. Alice Cooper came before him with a vaudevillian approach to shock rock, and Ozzy Osbourne is famous for biting off the head of a live bat on stage decades earlier. In the early 1990s, a group of artists including Marilyn Manson, Nine Inch Nails, My Life With Thrill Kill Kult, Ministry, KMFDM and Rob Zombie used keyboards and industrial music to push shock rock into a new era. Explorations between good and evil or beauty and the grotesque ensued.
