Even the Rehearsal Footage From Madonna's Rebel Heart Tour Is Spellbinding

By now we all know that Madonna in a live setting is an unstoppable force and one that few other pop performers even come close to.

She sings -- no lip-synching here, honey -- dances exquisitely, and plays electric guitar. Each new tweak to her stage costume is thrilling. Somehow all of it has a message and often subtext too.

Her backup dancers are also legendary and a huge part of the cornucopia of stage delights.

Two just-released teasers for Madonna's upcoming Rebel Heart world tour are each only 30 seconds long, but together they show that in this tour, like all her tours since the early 1980s, Madonna just may outdo herself -- again. This footage of the tour's new choreography, as well as a sneak peek of some costumes (nuns, anyone?), should get fans old and new excited.

The Rebel Heart tour was supposed to kick off in August in Miami, but Madonna postponed that to add more rehearsal time. "As my fans already know, my show has to be perfect," she explained in a statement. Now the festivities begin September 9 in Montreal.
