Madonna‘s Rebel Heart tour launches on Wednesday in Montreal, Canada, and the Queen of Pop has now given fans a peek at some of the incredibly hard work that’s gone into what’s sure to be a massive production extravaganza.

A video posted on Madonna’s Facebook page shows numerous dancers rehearsing their moves over and over while the song “Devil Pray” from the Rebel Heart album plays in the background. The dancers discuss how much they have to focus on their partners to get the moves right.

Later in the video, we see Madonna herself watching more dancers rehearse, while her song “Living for Love” plays in the background. She seems pleased with what she sees, but at one point, she says, “Bulls don’t have shirts, FYI. I mean, I need to see everybody’s bodies!” That’s likely a reference to the bullfight-themed video and performances she’s done in the past for “Living for Love,” where shirtless male dancers wearing bull heads dance around her.

Madonna also has been posting teaser photos and videos of some of the other tour numbers on her Twitter feed.

The star’s last trek, the MDNA Tour, grossed $305 million. The previous one, Sticky & Sweet, set a record for the highest-grossing tour ever for a solo artist, raking in $408 million.
