Behind the beautiful and storied Buell Theatre is a big, modest-looking brick wall where you’ll find an unassuming stage door. It’s easy to miss if you’re driving towards the Auraria Campus or downtown Denver, but it’s a vital portal through which all the theatre’s actors and crew enter, symbolic of the compelling behind-the-scenes efforts that make viewing theatrical performances there so magical. As such, it’s a fitting location for Catalysts, a recently installed community artwork by Jann Haworth that celebrates the individuals working behind the scenes in organizations that are so integral to Denver’s arts and culture.
