The John F. Kennedy Center for the Performing Arts, at 2700 F St. NW, is hosting its 20th annual free Open House Arts Festival Sunday from noon to 6 on multiple indoor and outdoor stages. Some of the performers were selected to celebrate the opening of the Smithsonian's new National Museum of the American Indian on the Mall.

The day begins at 11:45, with an opening ceremony on the North Plaza featuring the Lakota Sioux Indian Dance Theater. The troupe will go on to perform "Cokata Upo: Come to the Center," a story of the birth, death and rebirth of an Indian nation, at noon.

Other highlights among more than 30 free performances include concerts by the National Symphony Orchestra, the Washington National Opera and the Heritage Signature Chorale; dance by Hubbard Street 2 and the Washington Reflections Dance Company; and pop, jazz and folk music by Compact Jazz, Native Roots, the Radio King Orchestra and the South Austin Jug Band. Puerto Rican star Olga Tanon sings at 6 in the Concert Hall.

In addition, strolling performers will roam the center, the National Symphony Orchestra will corral a musical instrument "petting zoo," and the Capital Children's Museum will present arts and crafts activities and hands-on exhibits.

Free tickets for shows in the Terrace Theater, Theater Lab and Film Theater will be released in front of those theaters 30 minutes before they start. All halls are accessible to people with disabilities.

Parking at the center and surrounding streets will be tight, but the Foggy Bottom Metro station is just three blocks away, and free shuttle buses will operate all day. For information, call 202-467-4600 (TDD: 202-416-8524), or visit www.kennedy-center.org.
