Case studies in the volume include the Choctaw Cultural Center in Oklahoma and Choctaw sovereignty; a Black artist's autoethnographic performance challenging White audiences' entitlement to full inclusion; Immersive Van Gogh experiences and their scenographers; telephone performance during the COVID-19 lockdowns; Diane Paulus's The Donkey Show; the Battle of Atlanta panorama; an antebellum-themed department store display from the 1920s; escape rooms at Disney Parks; remotely staged plays about aging and dementia; tiki bars; anachronistic costuming at Renaissance Festivals; the technologies that shape the boundaries of immersive worlds; and tabletop role-playing games. Taken together, these essays contribute a rich discussion of immersive performance across radically different contexts, offering analytical models and terminology with which to clarify and advance this emergent discourse.
