Friday, Sept. 8
Awesome Sommerfest at the Goethe-Institut: No, it's not Oktoberfest yet. It's Sommerfest. The German cultural institute's end-of-summer open house includes free German lessons, karaoke in German and English, adult crafting, a screening of German short films and, in a nod to the locals, garage rock and noise-pop bands the Foul Swoops and Br'er. 3 to 9 p.m. Free.
ChiKo After Dark at ChiKo: Barracks Row fast-casual newcomer ChiKo launches a series of late-night pop-ups by letting chef Alex McCoy (Alfie's, Tchoup's Market) take over the kitchen. Look for Thai dishes, including pad mee korat and hoi lai nam prik pao, paired with Thailand's Leo Beer. No reservations are taken, so show up early. 10 p.m. to midnight. Free admission; food priced a la carte.
Return to Summer Camp at the Smithsonian Castle: Flash back to the days of handcrafted friendship bracelets, outdoor games, s'mores and campfire singalongs at the Smithsonian Castle and the adjacent Enid A. Haupt Garden. The big difference: This time, you're old enough to sip a cocktail. This party, sponsored by the Smithsonian Associates, features a performance by Mortified, with brave souls reading their teenage letters and diary entries about camp; live music and DJs; and a cash bar. 8 to 11 p.m. $30 in advance, $35 at the door; VIP tickets, which include an open bar and admission at 7 p.m., are $50 in advance and $60 at the door.
Saturday, Sept. 9
Rosslyn Jazz Festival at Gateway Park: For almost three decades, the Rosslyn Jazz Festival has drawn music fans to the downtown Gateway Park. This year’s lineup is topped by the Soul Rebels, an eight-piece New Orleans-style brass band that has performed with Nas and Big Freedia, and the driving throwback funk and soul of Lee Fields and the Expressions. When you’re not dancing, grab dinner from a food truck or have drinks in a beer garden. 1 to 7 p.m. Free.
Atlas Brew Works four-year anniversary party: Atlas celebrates four years in Ivy City with a party featuring exclusive beer releases, food trucks and live music by Small Time Thieves and Outside Smoke. Tickets include one beer — they're all $5 each after that — and a donation to the Living Classrooms Foundation. Noon to 7 p.m. $15.
Maryland Seafood Festival at Sandy Point State Park: The 50th annual celebration of the Chesapeake Bay’s bounty features vendors selling crab cakes, crab soup, crab fries, fried fish, shrimp baskets and oysters on the half shell. But it’s equally famous as the home of the Maryland Crab Soup Cook-Off, a crab-cake-eating challenge, and for crab-picking and oyster-shucking contests. Live music, chef demonstrations and activities for kids are featured throughout the weekend; Saturday closes with fireworks over the beach. 10 a.m. to 9 p.m. Saturday, 10 a.m. to 7 p.m. Sunday. Adults $10-$15; children and first responders admitted free.
Virginia Indian Festival at Riverbend Park: Members of eight tribes native to Virginia and the Washington area share their traditions, history and culture. Watch demonstrations, listen to talks, try archery and throw spears. Crafts, pottery and jewelry for sale at the marketplace. 10 a.m. to 4 p.m. $8.
Team Familiar at Strathmore: Last week, Donnell Floyd took to Instagram to hype a show that his go-go group, Team Familiar, was booked to play at Aqua, a bricks-and-mortar nightspot in Northeast Washington. “It reminds me of [legendary go-go venue] the Black Hole,” Floyd said into the camera lens of his phone. “The sound is bouncing off the walls, the people bouncing off the walls.” Go-go works a different kind of magic when it’s being performed under the stars, but it’s magic nonetheless — and Floyd will have the chance to prove it when Team Familiar graces the Strathmore lawn Saturday night. Indoors, the rhythmic rush of go-go music can make you feel as if you’re dancing inside a bag of microwave popcorn. Outdoors, it gives you the opportunity to two-step through a stampede without getting hurt. 7 p.m. Free.
Sunday, Sept. 10
Adams Morgan Day: This year, Adams Morgan Day will again shut down 18th Street NW between Columbia and Kalorama roads, making room for vendors, local artists and shops. Neighborhood restaurants, including Roofers Union, the Blaguard and Mellow Mushroom, will offer specials, and Songbyrd Music House has organized a stage for local musicians at the corner of 18th and Columbia. Noon to 6 p.m. Free.
Rumpus Room at U Street Music Hall: On weekends, DJs Stereo Faith and Meistro keep crowds dancing until the wee hours at Wonderland Ballroom, the Black Cat or Flash. But when they get home, they’re just “Dad.” Looking for a way to get their kids grooving to good music instead of the usual toddler-friendly fluff, the DJ duo has launched Rumpus Room at U Street Music Hall, a daytime party with cool tunes at a family-friendly volume and plenty of kid-friendly distractions, such as hula hoops and beach balls. Children can enjoy snacks, water and juice, and there will be brunch drink specials for parents. (The event is designed for children age 8 and younger, but older siblings are welcome.) 11 a.m. to 2 p.m. $10, or $30 for four tickets. Infants and crawling children admitted free. Maximum three children per adult.
Takoma Park Folk Festival at Takoma Park Middle School: The community's 40th celebration of folk in all its forms — string bands, singer-songwriters, West African drummers — features more than 50 performers across six stages, including one just for kids and teenagers. Browse a juried craft show, learn about community organizations or get lunch from one of 15 vendors. 10:30 a.m. to 6:30 p.m. Free.
14th Street Burger Battle at Cafe Saint-Ex: The second-annual hyperlocal neighborhood burger throwdown features grillmasters from Cafe Saint-Ex and District Distilling trying to take down defending champions Garden District. Tickets include sample burgers from all three restaurants, cooked on Saint-Ex's patio, while Shaw's Right Proper Brewing takes over taps inside. Twenty percent of proceeds will be donated to the Save the Children's Hurricane Harvey Children's Relief Fund. 4 to 8 p.m. $15.
