Fans of dissonant post-punk and red-carpet Oscar coverage have met their match. For Hollywood’s biggest night, the National Gallery of Art has presented movie lovers with the ultimate conundrum: Watch Joan Rivers crack wise about cleavage, or see a big-screen version of Instrument, director Jem Cohen’s 1999 film about Fugazi. In a recent interview with Express, vocalist/guitarist Ian MacKaye tried to explain the film’s appeal: “It’s not a narrative, but there’s a story. It’s not a concert film, but there’s music,” thus avoiding the static concert footage and rise-and-fall sequencing of most musical documentaries. In addition to Cohen, MacKaye and bandmate Guy Picciotto will be on hand to introduce the film. Just don’t expect an actual Fugazi performance: That’s about as likely as Winter’s Bone being crowned best picture.

INSTRUMENT SCREENS AT 5 P.M. AT THE EAST BUILDING AUDITORIUM OF THE NATIONAL GALLERY OF ART, 4TH ST. NW AND MADISON DRIVE. FREE. (202) 737-4215.
