ART

A PARADE OF VISITING EXHIBITS has passed through the sleek Inter-American Development Bank Cultural Center since its doors opened in 1992. This month the gallery will show off a handful of riches from the 30-year-old IDB collection of 1,500 paintings, drawings and sculptures by a slew of international artists. Among the gems in the eclectic show are Trinidad and Tobago artist Sonnylal Rambisson's "Rime of the Ancient Mariner," a startling semi-abstract red, gold and black woodcut of the sun, and American Martin Levine's etching "Waiting for My Train," which shows rails looping through a sea of skyscrapers. Three lithographs by one of Mexico's most famous sons, Diego Rivera, hang on the walls as well.

POP

WOODSTOCK AND ALTAMONT aren't the only famous music festivals of yesteryear. In 1976, Galax, Va., known previously for old-timey fiddle and banjo contests, was the site of Stompin 76, a three-day bluegrass festival that drew 150,000 fans to that sleepy little town. The promoter of the original festival, Hal Abramson, clearly has Woodstock-style revivalism in mind with Stompin 99, which will be held Friday through next Sunday at Buffalo Gap Camp in Capon Bridge, W.Va., about two hours from the Beltway. Once again, it's a stellar lineup, ranging from such popular acts as Doc Watson, Ralph Stanley, the Seldom Scene, IIIrd Tyme Out, the Nashville Bluegrass Band and Lonesome River Band to up-and-comers like Acoustic Syndicate and Fastest Grass Alive. There's even a bluegrass gospel show next Sunday morning and, as is the tradition at bluegrass festivals, there will be a lot of parking-lot and tentside picking going on.

CLASSICAL MUSIC

THE YOUNG SINGERS OF THE WOLF TRAP OPERA COMPANY finish the season with two performances of Mozart's "Magic Flute," a popular summer opera with autumnal associations, springlike good spirits and the chill of winter's hard truths. The production, originally from the San Francisco Opera, is designed by artist David Hockney, who, true to form, creates playful sets with a generous color palette. The production's menagerie includes a giraffe, a camel, a hedgehog and a lion, as well as a quorum of opera singers. Conductor Scott Bergeson, a regular at the New York City Opera and now the Metropolitan Opera as well, makes his Wolf Trap Opera debut.

--Philip Kennicott

At Wolf Trap's Filene Center, Vienna. Thursday and Saturday at 8 p.m. $17-$48. 703-255-1860.

FILM

BEFORE GANGSTA RAP CAME ALONG, rival crews boasted of their might more melodiously. Take, for example, "West Side Story," the 1961 movie musical that follows the escalating tensions between the Jets (all white) and the Sharks (all Puerto Rican). Maria (Natalie Wood) and Tony (Richard Beymer) are lovers caught in the middle of this melodrama inspired by Shakespeare's "Romeo and Juliet." The movie is part of a free outdoor series at the National Institutes of Health.
