“The Monster Ball Tour” was Lady Gaga’s second worldwide concert tour, and her most successful to date. The tour, in support of “The Fame” and “The Fame Monster,” was described as “the first-ever pop electro opera.”
Its theme changed over the course of the tour dates, which she had revamped a few shows in. Originally, Gaga was supposed to do a joint tour with Kanye West — when it was cancelled, “The Monster Ball Tour” was throw together in a short span of time.
The original theme of the show was human evolution (in respect to the theme of paranoia in “The Fame Monster”), but from 2010 on, New York City took center stage. Gaga and her dancers acted out getting lost in the city with the end goal of finding the Monster Ball.
