The sounds of our cities immediately plant us in a location, even if we’re not there physically. In D.C., that sound might be the incessant sirens of the presidential motorcade. In New York, in the days before no-honking fines were enforced, it would be the sound of a taxi driver aggressively beeping in traffic. For Nigerian artist Emeka Ogboh, the sounds that signify home are those of the Balogun, a large open-air market in Lagos. To create “Market Symphony,” his new installation at the National Museum of African Art, Ogboh recorded hours of sound; visitors to the museum’s first sound exhibition will hear music, buses and cars, and people exchanging goods. Listen even closer and stories start to emerge. Experiencing the sounds of home from the sterile confines of a gallery thousands of miles away becomes an emotional experience for Nigerian expats, who tell Ogboh that his work moves them unexpectedly. Even those who’ve never been to Nigeria can visit Lagos briefly before returning to the noise of traffic on Independence Avenue. The exhibition is on view daily, 10 a.m. to 5:30 p.m., at the National Museum of African Art, 950 Independence Ave. SW. Free. (202) 633-4600. africa.si.edu.
