 The show revolved around themes of evolution , as well as her paranoias represented on The Fame Monster . While developing the tour Gaga spoke about original sin and demons inside human beings ; " So we talked about growth , and that led us into this kind of scientific space , and we started talking about evolution and the evolution of humanity and how we begin as one thing , and we become another . " This theme of monsters and evolution played a part in the fashion for the tour , which according to Gaga was " another level from where we were with the Fame Ball . [ ... ] It 's going to be a truly artistic experience that is going to take the form of the greatest post @-@ apocalyptic house party that you 've ever been to . " Although Gaga stated that she was inspired by the things she and West were doing with the Fame Kills tour , she concluded that she did not want to use any of the things that they had designed together . Later , she said that Fame Kills was " the great lost tour " , but confirmed that some of the elements of it were incorporated into The Monster Ball .
