The Monster Ball Tour was the second worldwide concert tour by American singer Lady Gaga. Staged in support of her first EP, The Fame Monster (2009) and comprising a set list of songs from that and her debut studio album, The Fame (2008), the tour visited arenas and stadiums from 2009 through 2011. It is the highest grossing tour for a debut headlining artist in history. Described as "the first-ever pop electro opera" by Gaga, the tour was announced in October 2009 after an intended joint concert tour with rapper Kanye West was suddenly cancelled. The Monster Ball Tour commenced four days after the release of The Fame Monster in November 2009.
