Born out of the experimental genius of JTS Brown in 2002, 4 Square revolutionized long-form improvisation by stripping away sweep edits in favor of fluid and surreal scene transitions.

Now, as part of iO Theater’s 45th Anniversary, comedy legends Peter Grosz (Veep), John Lutz (30 Rock), and Rob Janas (Writer: New Looney Toons) reunite on their home turf as 3 Square. Expect a lightning-fast kaleidoscope of worlds, characters, and callbacks that weave seamlessly into one another. Come see why their signature style helped define Chicago improv.
