Saturday: Aug. 28 is the 50th anniversary of the March on Washington, and activities centered around the milestone will kick off this weekend and run through next week. Saturday, beginning at 8 a.m. at the Lincoln Memorial, thousands are planning to retrace the 1963 march's route through the city; there are also exhibits, bike tours and more all linked to the milestone event. Read more about the anniversary and what it will mean this weekend here.

Saturday:  The Dragon Boat Regatta is a summer tradition in the D.C. area, as teams from throughout the East Coast come to paddle the Potomac in 20-person boats spurred on by the cadence of a pace-setting drummer. When gliding down the river in synchronicity, it's a sight to behold. Races begin at 8:30 a.m. and continue until 4 p.m. at National Harbor,

Saturday: History buffs will could lose themselves in Decatur House's War of 1812 Open House, which features chances to roam the nearly 200-year-old home, listen to musicians performing songs of the early 19th century, learn War of 1812 trivia and see fashions of the day. The free event, which kicks off at 10 a.m., also offers kids activities, including lessons in making spyglass.

Saturday: Time was, an ice cream sandwich was just an ice cream sandwich. But the days of vanilla ice cream between two sticky chocolate pads are long over. The golden age of the ice cream sandwich is upon us, and Brightest Young Things celebrates with the Cookies & Cream Ice Cream Social, an all-you-can-eat cookie-thon with offerings from more than two dozen local sweet-makers,  including Ripple, Captain Cookie, Uncle Chip's and Shake Shack, all  from noon to 4 p.m. at Penn Social.

Saturday: Where many wine festivals put sips first and sounds second, the inaugural New Vintage Jazz and Wine festival at the Fairgrounds leads with its killer musical lineup. Curated by the jazz lovers at Capital Bop and the Petworth Jazz Project, the festival brings together New York guitar virtuoso Rafiq Bhatia, excellent local Afrobeat band Funk Ark and D.C. ensemble Kris Funn & Corner Store, plus painting performances from Art Whino's stable of artists. The wine? In this case, it's merely a bonus.

Saturday: The spare sound and conscious rhymes of Goodie Mob helped define Southern hip-hop in the 1990s; the Atlanta group is responsible for coining the term "Dirty South" on the single of the same name. Cee Lo Green is back in the fold after more than
a decade, having found success with Gnarls Barkley ("Crazy") and solo ("Forget You). Goodie Mob kicks off a national tour at the 9:30 club Saturday, just before the release of their first album in nearly 15 years.

Sunday: It has been a slow couple of weeks for concerts, but the Black Cat has been filling its stage with some interesting offerings this month from comedy to a summertime version of its holiday staple, Rock N Shop. Sunday brings "Throwing Shade," a live version of the women-friendly, gay-friendly comedy podcast from television writers Erin Gibson and Bryan Safi (who has written for the likes of "The Ellen DeGeneres Show").
