PRNewsFoto/Live Nation EntertainmentIt seems like it’s been a long time coming, but Madonna‘s Rebel Heart tour finally gets under way tonight in Montreal, Canada. The start date of the trek was originally August 29 in Miami, but it was moved forward to allow more time for Madonna, a notorious perfectionist, to get everything just right. So what can fans expect? Her producer tells ABC Radio, “It’s just gonna be crazy.”

Diplo, a top DJ and one of the producers who worked on Madonna’s Rebel Heart album, also will open for her Wednesday and Thursday night in Montreal. He tells ABC Radio, “I’m not sure anybody’s gonna know who or what I am, but hopefully I can surprise ’em and give ’em something new, y’know — just warm ’em up, let ’em know that Madonna’s about to shut down the whole arena!”

He adds, “She’s been working on the live versions of the songs for, like, three to four months, so it’s just gonna be crazy.”

Madonna has already revealed her set list will include classics like “Dress You Up,” “Who’s That Girl,” “Vogue” and “Holiday,” plus a big helping of songs from Rebel Heart because, in general, as she told Entertainment Weekly, “I’m not a ‘greatest hits’ kind of girl.” She added, “You could say it’s reinventing, but a real artist is continuously changing and evolving because the art is continuously changing and evolving.”

The Rebel Heart tour will visit North America, Europe, Asia, Australia and New Zealand before wrapping up March 27. Madonna’s shows in Australia will be her first Down Under in 23 years, and she’ll do her first-ever shows in New Zealand as well.

Madonna has a lot to live up to when it comes to raking in the bucks on tour: her 2008 Sticky & Sweet tour still holds the records for the highest-grossing tour by a female artist, the highest-grossing tour by a solo artist, and the second-highest grossing tour of all time, behind only The Rolling Stones’ A Bigger Bang tour. Her last tour, the MDNA tour, ranks in the top ten highest-grossing tours of all time.

Of note, Madonna’s opening act for three shows in her current hometown of New York City will be red-hot comedian Amy Schumer.
