In addition to producing new works at the Gorki, Langhoff brought with her a couple of productions from Ballhaus Naunynstraße, including Crazy Blood , which still sells out every performance. Over the stage hangs a piano, tilted perilously at an angle.

But when Frau Kelich threatens her Turkish students with a pistol, her gunshots explode just as loudly.
