Nana Shineflug's troupe continues to be a training ground for some of the best dancers in the city. Her choreography is full of the wonders of spiritual self-discovery. Wherever Shineflug travels (Java, for instance), influences of that culture show up in her dances. Always inventive and always moving, this modern dance takes viewers to strange and wonderful places. Performances at: Athenaeum Theatre (2936 N. Southport Ave.) and Harold Washington Library (400 S. State St.).
