Lin-Manuel Miranda is heading back to Broadway, this time transforming the freestyle hip-hop collective he co-founded back in 2004 into an improvisational theatre piece.

Miranda announced Freestyle Love Supreme on The Tonight Show, telling Fallon that the show will be “entirely made-up“, featuring a rotating cast of surprise guests.

The description on the show’s website says there’s no way of knowing who will appear on any given night, including whether or not Miranda himself will be there:

Part of what makes Freestyle Love Supreme so unique is its unpredictability. Every show is different in material—and in who appears on stage. Lin-Manuel is a founder, producer, and friend of the show, and at any given performance, he may or may not be part of the cast. Other special guests might include Christopher Jackson, Daveed Diggs, Wayne Brady, James Monroe Iglehart, and many more!

The show, created by Miranda, Anthony Veneziale, and Thomas Kail, will have a core cast consisting of Neziale, Andrew Bancroft, Arthur Lewis, Bill Sherman, Chris Sullivan, and Utkarsh Ambudkar.

The show will run on Broadway for 16 weeks. If this sounds like the sort of thing that you’re willing to get your butt all the way to New York for, tickets for the show go on sale in early July.
