I think I can speak for all Bonnaroovians when I say the Bonnaroo Comedy Theatre is a ridiculous pain in the ass to negotiate. Since it’s one of the few air-conditioned refuges from the elements, you wind up having to fight with hundreds of burnt-up burnouts for your space on a bench to see jokes. Which is why I’m thrilled beyond words that Mike Birbiglia will appear for two nights at Zanies prior to his shows with Michael Che at Bonnaroo. Birbiglia, a contributor to This American Life and The Moth, is a storytelling comedian, and his shows Sleepwalk With Me and My Girlfriend’s Boyfriend have garnered major critical acclaim for their runs off-Broadway. Birbiglia weaves stories that have smart, emotional arcs while still focusing primarily on comedy. Although his intentions are squarely on working out new material — this is the first stop on his “Working It Out” tour — his talents are massive enough you likely won’t even notice the lack of polish.
