The Baltimore Improv Group is trying to change the face of comedy. Literally. Which faces are not seen? Who is not heard? Queer, trans, non-binary, even women often struggle for a place in comedy. BIG’s response is XFest -- four days of performances and workshops that celebrate gender minorities in comedy. We meet festival organizers Julia Hall and Hallie Herz and transgender standup comedian Violet Gray, who talks about how comedy can combat prejudice.
