Last night, I attended the final dress rehearsal of Moving Theater’s Armory Show, a genre-blurring piece created during the company’s eighteen-month residency at the Park Avenue Armory.  Saturday night’s performance is already sold out, but tickets are still available to the 5 PM and 8 PM shows on Sunday.  Created by MT’s founders, Brennan Gerard and Ryan Kelly, the new work blends dance, live video, text, and music as it moves through the armory’s landmark period rooms. In a nutshell, Armory Show is an intriguing mess.  The performers explore memory, history, the military, and gender – specifically, male identity through ballet vocabulary – in the context of the armory’s lush décor and areas of decay.  Armory Show might be frustrating and confusing, but in the best way possible.  You won’t be bored, but make sure to gaze up at the ceiling in every room.  It’s full of surprises.
