The experimental production Confidential Musical Theatre Project makes its Chicago debut with, well, no one knows exactly. Avra Fainer and Steve Lavoie cast the top-secret musical, but even the performers won't meet each other until an hour before the show; everyone involved rehearses on their own time and just prays that everything comes together. "You want to put a show on, and there's so many logistics you have to deal with," Fainer says. "I want a way to put a show on without all those components." The concept has had success across the country with impromptu performances of Sunday in the Park With George and A Little Night Music. "Audiences don't believe that they haven't been rehearsed prior," Fainer says. But part of CMTP's mission is to mount shows that aren't performed often, so don't expect a beloved Broadway classic. Don't expect anything expect surprise, which is half the fun of a confidential musical.
