Madonna and her Dancers Rehearse for Rebel Heart Tour (rollingstone)

Madonna doesn’t embark on her Rebel Heart World Tour until September, but the singer has shared a pair of teaser videos that give fans a behind-the-scenes look at the intense, high-energy rehearsals for the six-month-long international trek.

In the first teaser, soundtracked by Rebel Heart‘s “Devil Pray”, fans get a peak at the various costumes – nuns on stripper poles, a flamenco-inspired routine – and sophisticated dance moves that will go into each show. There’s also a glimpse of Madonna herself preparing for the string of performances. In the second video, featuring “Iconic”, fans witness the epic scope of the touring production as dozens of dancers rehearse atop elaborate sets armed with props.

Madonna’s Rebel Heart Tour will kick off September 9th at Montreal’s Bell Centre. She’ll continue to hit North American arenas throughout September and October before heading to Europe for two months. Diplo will serve as Madonna’s opening act for the Quebec gigs, while comedian Amy Schumer will open for the singer’s New York-area shows. In January, Madonna will return stateside to fulfill her five postponed concerts and then chart course to Asia and Australasia. The Rebel Heart Tour will conclude March 27th, 2016 in Brisbane, Australia.

The tour was originally scheduled to begin on August 29th in Miami, but Madonna postponed the first five shows in order to add more rehearsal time. “As my fans already know, the show has to be perfect,” Madonna said in a statement. “Assembling all the elements will require more time than we realized. I apologize for any inconvenience this may cause my fans. I can promise you this show will be worth the wait. Can’t wait to share it with all my Rebel Hearts out there.
