The weekend’s best nightlife, music, art and other events. For even more, check out Nightlife Agenda.

Friday-Sunday: Artscape, Baltimore’s 33rd annual outdoor celebration of culture, returns with a lineup of sweltering heat, experimental art and music. Fill your ears with headlining sets from Sharon Jones & the Dap-Kings (Friday), Galactic (Saturday) and Anthony Hamilton (Sunday); for your eyes and other senses, there’s a weekend-long lineup of aerialists, needle swallowers, street theater, stand-up comedy, a silent disco dance party and many other oddball attractions, all of it blissfully free. Thankfully, there’s an Artscape app to help you navigate the sea of options. Events take place in the neighborhood surrounding the Maryland Institute College of Art (1303 Mount Royal Ave.). Plan your weekend in Baltimore: Where to eat, sip and see art now.

Through Saturday: If you're Baltimore-bound for Artscape, consider making a reservation for Chef Jeremiah Langhorne's takeover at Artifact Coffee, a chance to catch the young District-born chef in action before the opening of his own restaurant in Washington. Langhorne will prepare his modern cuisine for a series of a la carte dinners with B'more's Spike Gjerde from 6 to 10 p.m. through Saturday. Langhorne plans to forage many of the ingredients for the dinner. Read: Will Jeremiah Langhorne be the next Rene Redzepi?

Saturday: Burgers. Beer. Charity. That’s the elevator pitch for the first D.C. BRGR Bash, which pairs signature offerings from 10 local burgersmiths with $5 pours of DC Brau, Atlas Brew Works and New Belgium beers. You’ll be able to eat tasty patties from the likes of Burger Tap & Shake, Boundary Stone, 1905, Granville Moore’s and others. Fifty cents from every burger sold will benefit a charity of each participating restaurant’s choosing. Noon to 6 p.m. in the lot at 945 Florida Ave. NW. Admission ranges from $30 to $50 for five to 10 burger samples.

Saturday: At most beer festivals, you just stand around and drink beer. Not at the annual 3 Stars Artists and Artisans festival hosted by 3 Stars Brewing Company, an event dedicated to showcasing local musicians, graffiti artists, clothing designers, food trucks and distillers. Among the highlights of the festival: A set by buzzworthy rock band Spirit Animal, graffiti art, food truck snacks and a tasting with New Columbia Distillers. There also will be plenty of 3 Stars beer, of course, from 1 to 6 p.m. $15 admission; food and drinks are extra.

Saturday: Forget fresh beets and local tomatoes: On Saturday, Union Market will be celebrating ice cream, the only seasonal product that really matters. For the fourth annual DC Scoop festival, 15 frozen-treat vendors will face off to see who makes the best ice cream in the District. Though the winner will be selected by a panel of expert judges, there also is a people’s choice category, meaning it’s pretty much your democratic duty to try all 15 options from 1 to 4 p.m.

Saturday: After the near-cancellation of Fort Reno, some wondered about the fate of the Fort Dupont Summer Concert Series. But the popular free series is in fact a go, kicking off an abbreviated season this weekend with Nappy Riddem performing with Christylez Bacon and Maimouna Youssef with DJ Jahsonic. The concerts run from 7 to 9 p.m. every Saturday through Aug. 9. (Shows at Carter Barron pick up the slack next month, beginning with the Going Out Guide's Reggae Night on Aug. 8.)

Saturday-Sunday: How good are you at spotting a lie? Put your shrewdness to the test at "Perfect Liars Club," an interactive storytelling show in which four people tell tales, but one isn’t true. Following the stories, audience members have the opportunity to grill the performers to see if their stories unravel. But be warned: You will very likely be duped. The show is just one of the standouts of the Capital Fringe Festival, which continues through July 27. Shows are Saturday at 10 p.m. and Sunday at 7:15 p.m. at Goethe-Institut; admission is $17, plus a one-time purchase of a $7 Fringe button.
