In retrospect, an event like Open Cirque was inevitable. In a city famous for open mics, open minds, and open morals, it was only a matter of time until someone put together an open-stage circus show. And yes, the show is exactly what it sounds like. The program reads simply, "Act 1, Intermission, Act 2." All types of performance artists are welcomed, and stage time is divvied up on a first-come, first-served basis. This low-pressure, casual environment creates a chance for performers to take risks, try new material, and network — and a chance for the audience to get a first look at the next big thing in Bay Area circus. It can be hard to predict what type of acts will show up for an open stage, but the event is produced by the Ministry of Flow, which is best known for "flow arts" like contact juggling, staff spinning, and acroyoga.
