About
iO opens its 45th-anniversary celebration with alumni, current teams and generations of improv.
This is a milestone night for a theater that helped define Chicago long-form improv, bringing influential alumni together with the performers carrying that tradition forward. The reunion factor makes Thursday’s opening more consequential than an ordinary night of house-team shows.
