Jazz in the Garden at National Gallery of Art Sculpture Garden: Washington’s favorite first date is back: Kicking off the weekly Jazz in the Garden summer concert series is the group Matuto, known for a mash-up of bluegrass and Brazilian sounds. The following week’s act is the U.S. Coast Guard Dixieland Jazz Band, a seven-piece group that performs New Orleans classics around the country. Through Aug. 25. 5 p.m. Free.
“Trolley Car Mail” at National Postal Museum: In 1892, St. Louis began delivering mail by trolley. By 1908, such cities as Boston, Chicago and the District had followed suit. The move allowed the Postal Service to deliver mail three or four times a day in some urban areas. This exhibition looks at how trolley cars helped to revolutionize the mail system before they fell out of favor when the Postal Service began using trucks. Through Sept. 10. Free.

Second anniversary party at Ocelot Brewing: Which local brewery makes the best IPAs? That’s a tough question, but in-the-know beer geeks should have Ocelot at or near the top of their list. The brewery celebrates its second anniversary with a huge blowout party, featuring 15 house-made beers, including some made just for the event, and 18 guest beers. Entertainment comes from a jazz band and the Phish tribute act the Last Rewind — after all, Ocelot is named after a Phish song. Noon to 7 p.m. $35 in advance and $40 at the door, include six beers and an anniversary glass.
Brambleton Brew Fest at Brambleton Town Center: The annual Brambleton Brew Fest, or Bram Brew Fest, brings more than two dozen breweries to the Brambleton Town Center. The vast majority are from Virginia, including Blue Mountain, Chaos Mountain, Pale Fire and Caboose, but there are also representatives from Maryland and Pennsylvania. Food trucks and live music round out the day. Adult tickets are $30, which includes six five-ounce samples. Admission is $10 for children aged 13 to 20; children 12 and under are admitted free. The $50 VIP tickets include brunch at Lost Rhino Retreat from 11 a.m. to noon, followed by early access to all beers. Noon to 6 p.m.
Washington D.C. Dragon Boat Festival at Thompson Boat Center: Now in its 16th year, the festival is intended to raise awareness of Taiwanese culture by showing off some really cool boats. In addition to watching the races, visitors can check out exhibitions, craft demonstrations and the crazy-strong biceps on the rowers. Through Sunday. 8:30 a.m.-5 p.m. Free.
Gaithersburg Book Festival at Gaithersburg City Hall grounds: The annual book festival returns with workshops, talks and signings featuring more than 100 authors.

Taste of Arlington on Wilson Boulevard: This annual street festival — on Wilson Boulevard from North Randolph Street to North Monroe Street — is celebrating its 30th year with bands, a dog-friendly family zone and a beverage garden, featuring beers from national breweries as well as such locals as Mustang Sally, New District and Heritage. But the main attraction for the more than 50,000 expected attendees is the food: More than 50 restaurants and food trucks, including Kapnos Taverna, Liberty Tavern, Courthaus Social and Texas Jack’s, will have small plates and bites available for $1-$5. Noon to 6 p.m. $10-$15.
Garrison Keillor at the Lincoln Theatre: He put his iconic public radio show, “A Prairie Home Companion,” in his rearview mirror last fall, but Garrison Keillor hasn’t exactly retired. The 74-year-old storyteller has filled the extra time in his schedule with writing — he has a weekly column in The Washington Post — and touring the country with a variety of shows. His stop at the Lincoln is billed as “An Evening of Storytelling,” which means no props, singing or noisemakers: just one of the best in the business of spinning yarns and telling tales, tall or otherwise. 6:30 p.m. $55-$95.
“America Collects Eighteenth-Century French Painting” at National Gallery of Art's West Building: Before the French Revolution descended into chaos, the country’s painters mainly occupied themselves with intricate paintings of rouged women, dapper men and children in ruffs. When Napoleon’s elder brother came to the United States in 1815 with some of this art in tow, the country was captivated. The National Gallery has assembled 68 of the finest works of 18th-century French art held in American museums, including pieces by the Rococo artist Jean Honoré Fragonard and the neoclassical master Jacques-Louis David. Through Aug. 20. Free.
The Revelers at Hill Center at the Old Naval Hospital: As part of the Hill Center’s American Roots concert series, the Revelers are coming to town with their blend of Louisiana folk. In true Cajun fashion, a fair number of the group’s songs are in French: If you’re not bilingual, don’t fret — you’ll enjoy them if you speak accordion, saxophone and growling electric guitar. 4 p.m. Free, register online.
