"Behind the Stucco Façade of the Sickle Museum" is being put on by public engagement artist-in-residence KCHUNG Radio. To access the unfolding plot, audience members can check out handheld radios that are triggered by transmitters placed throughout the museum. On opening day, Saturday, Dec. 7, live actors will accompany the recorded transmission. Mystery Play will run from 1 to 4 p.m. until Dec. 20. For more information.
