 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.
