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