What: National Symphony Orchestra‘s tribute to the legends of D.C. music.

When: Gates open at 5 p.m. and the the show starts at 8 p.m., Sunday.

Where: West lawn of the U.S. Capitol. The show will be moved to the Kennedy Center if it rains (call 202-416-8114 after 2:30 p.m.).

Cost: Free.

Why you should go: There are two D.C.’s, but both of them will come together for this event. When else can you hear go-go played on the U.S. Capitol lawn, and by our nation’s symphony orchestra no less? The music of D.C.’s own Duke Ellington, John Philip Sousa and Chuck Brown will be showcased. The show will also be a sort of birthday celebration for Brown, the “Godfather of Go-Go,” who turns 75 this year.

Other events to consider: Saturday is the last day to take advantage of Free Summer Saturdays at the Corcoran Gallery of Art at 500 17th St., NW. Admission, which normally costs $10, is free on Saturday.
