Last week, we gave you the heads up about Exponential Festival, a cavalcade of local productions that are “all experimental and strange in nature, but in a way that’s experimenting with the idea of experimental theater,” according to founder Theresa Buchheister. With the fest continuing through Sunday, we checked in to see how it’s going. Watch our video for a taste of the shows at The Brick, Cloud City, The Silent Barn and The Bushwick Starr.
