When the American Theatre of Actors presents Tango Fusion during the first week in December, the gimmick will be that New York City audiences will get the chance to dance.

That's the word from production sources at Stepping Out Productions, which is presenting Tango Fusion the world's first interactive tango piece. Created by Diane Lachtrupp and directed by Michael Yawney, Tango Fusion will feature live music from Tanguardia. In the show, Lachtrupp and her dance company perform a brief history of Tango in its various styles before inviting the audience to join in.

The cast for Tango Fusion features Diane Lachtrupp, Johnny Martinez, Sarah La Rocca, Jak Karako, Audrey Martinez, Manuel Rojas, Mariana Parma and Carlos Acuna. The show will be choreographed by the company.

The American Theatre of Actors is located at 314 West 54th Street., between Eighth and Ninth Avenues.

Tickets will be $32 for all seats; call Ticket Central at (212) 279-4200, or visit www.brettsinger.com/nowplaying. -- By Murdoch McBride
