Planning is so overrated, or at least you might think so after seeing Off Book: The Improvised Musical. Jessica McKenna and Zach Reino will take the stage armed with their wits and little else and will create an entirely improvised musical right before your very eyes and ears. The duo regularly work with big name comedy folk including Maya Rudolph, Andy Samberg and Amy Poehler. We don’t know what will happen exactly, but we can almost guarantee it will be memorable.
