This week, check out musicians at the NSO, dance to New Orleans funk at Millennium Stage and catch the tail end of the National Gallery’s Lichtenstein exhibit, all for free. Here’s a daily rundown:


Two closings at the Art League Gallery

This is your last chance to see two shows at the gallery: “Up Close & Personal,” a display of colored-pencil portraits by Suzanne Vigil, and an all-media exhibit featuring works made from a variety of materials.


National Symphony Orchestra Chamber Concert

Ticket prices to shows at the Howard Theatre tend to be hefty. On Tuesday, though, see a show for free when NSO musicians perform works by Bolling and Gershwin as part of the “NSO in Your Neighborhood” series.


Corcoran Uncorked

The museum debuts its new after-hours event with a free kickoff. The museum stays open for free from 5 to 9 p.m. There are docent-led tours at 6:30 and 7 p.m. At 7, check out the MobileMovie Film Festival, a collection of cellphone videos by local filmmakers.

5 to 9 p.m. Corcoran Gallery of Art, 500 17th St. NW. 202-639-1700.


Big Sam’s Funky Nation

This New Orleans-based band plays just what you would expect: urban funk with an especially full, raucous sound. Expect brass, and lots of it, when former Dirty Dozen Brass Band member Big Sam brings his crew to Millennium Stage.


‘Dirty Harry’

Clint Eastwood may be known these days for a speech to an empty chair, but this 1971 police action thriller will remind you what made him a star more than 40 years ago.


‘The Poetic Dimensions of Symbols and Shapes’

This show features sculpture by Pattie Porter Firestone and paintings by Andrea Barnes. It closes at the Zenith Gallery on Saturday.


Last chance for Lichtenstein

The National Gallery’s Roy Lichtenstein exhibit closes Sunday, so hurry to see works by the pop artist from every major period in his career before the show hits the road for London’s Tate Modern.
