AntiGravity: An American Band, a 60-minute tribute to the enduring spirit of New York City, will be performed at New York City's Exit Nightclub on the first anniversary of the Sept. 11 attacks.

AntiGravity, which was founded in 1990 by Christopher Harrison, first performed An American Band during the 2002 Olympic Winter Games in Park City, Utah. The show was performed nightly for nearly two months to enthusiastic response.

The show — exploring confusion, anger, hopelessness, kindness, selfless compassion and renewed patriotism — was created after the events of Sept. 11. On that morning members of AntiGravity were to workshop a new children's show for 42nd Street's New Victory Theatre. Instead of the workshop, the company members spent their time creating an outlet to express the emotions they were feeling. From that came An American Band, a stage/aerial performance told without words.

AntiGravity: An American Band will be performed on Sept. 11 at 9 PM at Exit Nightclub, which is located at 610 West 56th Street (between 11th and 12th Avenues). There is a $20 cover at the door, which will benefit Broadway Cares/Equity Fights AIDS.
