What do Zen and cabaret have in common? Nothing, unless you're Nina Rolle. The artist describes Zen Cabaret as "a traveling medicine show that pitches a tent in whatever town it's in, and then these rogues show up and put on a production." Most recently, Rolle pitched her Zen tent in Boulder for Zen Cabaret Version 6.5: Play Money, complete with audience-interaction elements, a soundtrack provided by Jayme Stone and absurdist retail therapy. "In a way, the whole thing is a practice of how I like to laugh, the kind of laugh I want to bring to people," Rolle explains. So chuckle it up.
