Combining modern dance, gender-bending camp, lunatic conceptual comedy, and shockingly ambitious hair and makeup, the Cherdonna and Lou Show is like nothing you’ve ever seen. Their latest production out out there (A Whole Night Lost) finds the Seattle duo navigating a creepy dreamscape of missed connections, smashed plaster, full-frontal nudity, and quietly breathtaking dance. The whole thing wraps up with an old-school lip-synch that blasts past irony to something old and new and pure. It’s hilarious dance-theater magic. (Washington Hall, 153 14th Ave,, 8 and 10 pm, $20)
