Improv isn’t just “Can I have a non-geographical location?” – this year, the theme of the 15th annual IMPRO festival is “Borders. Limits. Liberty.” They’ve invited improvisers from Algeria, Lebanon and Syria for the showcase, A Place to Be (Mar 14, 15, 17, 20:00). The piece promises to model intercultural contact in miniature: strangers meet and fail to understand each other, eventually finding a shared language and developing a scene. It’s hosted by Die Gorillas, old hands since 1997.
