Acclaimed Polish troupe Teatr Cogitatur pulls off a tour de force of chiaroscuro lighting, physical performance, and arresting image in this haunting tribute to a tragic artist and his breathtaking, terrifying visions. Romantic poet Friedrich Holderlin, a contemporary of Schiller and Hegel, died addled and obscure in 1843 but has since been recognized as a talent in the neighborhood of Goethe or Rilke, an ecstatic classicist also significant to avant-garde critical theory. You can number Nietzsche and Heidegger among his no-surprise-there champions, and credit Holderlin as among the first to seize upon the spooky Greco-Teutonic mythological fusion central to Nazi ideology. Ol' black magic aside, Holderlin was a disillusioned child of the Enlightenment, broken by failed love and firsthand witness of his ideals in action in Revolutionary France; this expressionist collage, part biography and part performance study, touches on both in the course of a thoroughly riveting hour. Through 11/7: Sat 8 PM, Sun 5 PM. Chopin Theatre, 1543 W. Division, 773-278-1500. $15-$22. Closing.
