Upright Citizens Brigade

Possibly the most famous improvisational comedy troupe in America, the Upright Citizens Brigade was started by Chicago's ImprovOlympics members in 1990. Several of the performers - like Amy Poehler, Matt Walsh, Horatio Sanz and Will Arnet - have gone on to have successful comedy careers in stand-up, both on Saturday Night Live and in feature films. The ever-evolving troupe performs seven nights a week in Los Angeles and New York, frequently including other touring comedians on-stage.
