This dance is about falling, but nobody would get that but me," says choreographer Nana Shineflug about her Bach Suites. "It's one of those deep philosophical things," she says, mugging as she says "deep" and "philosophical." "We fall into the world, and the world is filled with problems and difficulties. What you do on the physical plane is get up and try to engage joyfully in the dance of life. You keep falling, but just getting up and trying to reengage is the name of the game. It's figuring out how to do it joyfully." Like many of Shineflug's dances, Bach Suites tries to capture a moment; here it's the moment of transcendence she describes. The piece includes some literal falling, but its signature is smiling dancers who leap and turn and gambol to Bach solo cello pieces. Shineflug's Chicago Moving Company seem to be having fun with her open, expansive movement, but my favorite section was a more pensive duet in which Holly Quinn and Eileen Sheehan echo each other's movements, as if they were melodies in counterpoint. The program also includes Shineflug's gritty Crash and Burn and Bob Eisen's new Park Works. Friday and Saturday and next Friday and Saturday, June 28 and 29, at 8 at the Dance Center of Columbia College, 4730 N. Sheridan; $10-$12.
