OUR PICKS

Exhibition

Lumped together under the name "Traveler," in an allusion to both space and time, are two separate installations by Cai Guo-Qiang open Saturday at the Hirshhorn Museum and Sculpture Garden and the Arthur M. Sackler Gallery. At the Hirshhorn, the Chinese artist's gunpowder drawings -- sketches for a planned series of large-scale explosions -- go on view, while the Sackler features the weathered hull of a Japanese boat resting on a porcelain sea. Call 202-633-1000.

Music

Toni Blackman, founder of Washington's acclaimed Freestyle Union, has championed hip-hop culture for more than a decade. She continues that mission Friday at the Lincoln Theatre in "Black Expressions -- Music!!!," featuring such like-minded souls as hip-hop theater artist and singer-songwriter Psalmayene 24 (Gregory Morrison), the Poem-Cees and Erykah Badu. Call 202-397-7328.

Film

Alexander Payne and Jim Taylor's "Sideways" is a rich comedy about two men (Paul Giamatti and Thomas Haden Church) and their last hurrah through California wine country before one of them gets married. It's one of the funniest movies of the year. See review on Page 33.

Dance

Jazz dance, with its syncopated rhythms, dynamically punctuated steps and that gorgeously rich musical canon, takes center stage on Wednesday at George Mason University's Center for the Arts. Billy Siegenfeld's smartly sophisticated Jump Rhythm Jazz Project arrives from Chicago with a program that includes "For Buster," an homage to a legendary tap dancer and member of the Copasetics, James "Buster" Brown. Call 703-218-6500. The troupe also appears at Dance Place Nov. 5-7; call

202-269-1600.
