Gaga has described the revamped show, which recently ran from February to April abroad, as "more of a musical and less of a concert."

"It has a New York theme. It's a story and the story is that me and my friends are in New York and we're going to the Monster Ball, and we get lost," Gaga told Ryan Seacrest on KIIS FM in an interview last month.
