Long-form improvisation is a unique art form that stresses agreement, honesty, intelligence, support, and collaboration. A group of improvisers takes a single audience suggestion and works as a group using a “group mind” to weave thoughts and themes inspired by the suggestion to help them create a world filled with wonderful characters and story lines. The result is sometimes hilarious, sometimes poignant, but always wonderful!
