Alice Cooper
On July 1, 2007 Cooper performed a duet with Marilyn Manson on Manson's "Sweet Dreams (Are Made of This)" and Cooper's "I'm Eighteen" at the B'Estival event in Bucharest, Romania. The performance represented a reconciliation between the two artists; Cooper had previously taken issue with Manson over his overtly anti-Christian onstage antics, which included tearing up bibles, and he had sarcastically made reference to the originality of Manson's choosing a female name and dressing in women's clothing. Cooper and Manson have been the subject of an academic paper on the significance of adolescent antiheroes.
Alice Cooper joined with Marilyn Manson to form the Masters of Madness Tour in 2013. Marilyn Manson performed two solo shows before joining Cooper in Albuquerque, New Mexico on June 1, 2013 to kick off the month long tour.
