Making its debut at URBAN-15 during the first weekend of November, Invocation is a new performance art piece by San Antonio performance artists Erik Bosse and Laurie Dietrich. An experiment in enhanced storytelling, Invocation consists of a pool of short stories (two to three minutes each), paired with photographs and soundscapes. At each performance, a few of those stories will be selected, in random order, to be shared. As projected images appear and disappear and the soundscape builds, a story emerges — or, more likely, as many stories as there are people in the room.
