Eric Lane Barnes has put together a show that’s surprisingly terrific, if a little rough. His story revolves around a concentric circle of religious conversions: First, there’s baby evangelist Jimmy (Dylan Zucati, playing a role based on a real-life uncle), who wants to “play church” even as a pre-teen. Some 35 years later, his nephew Guy (Bobby Temple) falls under the spell of his best friend’s mom, the recently converted Eileen (Alyssa Keene), whose daughter Bethany (Lauren Kottwitz) is a sort of post-Goth Mama Cass with a filthy mouth, a none-too-secret crush on Guy, and alto pipes that ring out across the Balagan like a cathedral bell. There’s a certain amount of repetition as we witness the characters transported by their own experience of demons and the Great Beyond. But the clutter clears often enough to see that Barnes’ characters are distinct, and they’re all fighting in the playwright’s mind for stage time they deserve.
