“Improvising brings us into a living model of social openness—a model of people interrelating to each other through the practice of listening—in the midst of a world in which people so often retreat behind the boundaries and tensions of academic, political, racial, cultural cubbyholes, and all the other prefabricated borders that divide us.”

– Stephen Nachmanovitch
