What is Improv? Improvisation, or improv, is a form of live theatre in which the plot, characters and dialogue of a game, scene or story are made up in the moment. Often improvisers will take a suggestion from the audience, or draw on some other source of inspiration to get started. Improv is spontaneous, entertaining, and fun. But like all great things, you’ll have to see it first hand to fully experience and appreciate it. Improv at the Tower is dedicated to “Make America Laugh Again”..
