5. Lady Gaga's 'Monster Ball'
Lady Gaga's 'Monster Ball' tour came out of nowhere at the tail end of 2009 after a joint jaunt with Kanye West was axed at the final hour. Dubbed the 'first ever electro-pop orchestra', the tour kicked off just four days after 'The Fame Monster' was released. In these early stages Gaga was apparently seen putting the final touches to the stage less than an hour before showtime.
