Fort Reno Concert Series , Mondays and Thursdays through Aug. 2

For 50 years, an outdoor stage in Fort Reno Park has hosted some of the city’s finest punk and alternative bands, including Fugazi, Unrest, Priests and Q and Not U. To celebrate the series’ 50th anniversary, organizers launched a Kickstarter campaign that raised more than three times its $4,000 goal, allowing them to extend the concert season into August. Highlights on the not-completely-finalized schedule include Messthetics, which features jazzy guitarist Anthony Pirog with Fugazi’s rhythm section, on July 12, and a reunion of ’90s metal-funk trio Branch Manager on Aug. 2. 7 to 9:30 p.m. Free. — Fritz Hahn

‘Fun House’ at the National Building Museum , July 4 through Sept. 3

The National Building Museum’s annual “Summer Block Party” installation has brought a maze, icebergs and hivelike structures to its massive Great Hall in recent years. This time, the museum is bringing back one of its greatest hits — sort of. “Fun House” celebrates the 10th anniversary of Snarkitecture, the New York design studio that created “The Beach,” the wildly popular pool filled with almost a million plastic balls that made D.C. hipsters act like kids during the summer of 2015. “Fun House” features a full-sized house with interactive rooms, and a “backyard” pool filled with hundreds of thousands of balls. (Just remember to secure your wallet and cellphone before you take a dip.) Adults who want to enjoy the museum can book tickets for the Late Night events on Wednesdays, which include talks and pop-up bars, and Sunday yoga sessions. Times vary. $10-$16. — F.H.

Capital Fringe Festival , July 7-29

This year’s hodgepodge of eccentric theater is more concentrated than ever: Within a few minutes walk of the Waterfront Metro, you can see around 80 experimental plays, including oddball comedies, musicals, dramas and Shakespeare adaptations. This year also brings something new to the festival: five plays either curated or produced by the Fringe organization itself. They include “O Monsters,” created by Philadelphia’s New Paradise Laboratories; “Barococo,” by D.C.’s Happenstance Theater Company; and “Andromeda Breaks,” a police procedural starring the Classical Greek damsel in distress. Some events are free; ticketed shows $17. All shows require the one-time purchase of a Fringe button, $5-$7. — Sadie Dingfelder

If you want to see the biggest pop stars in D.C. this summer, you’ll have to make the trek to the biggest venue that the area has to offer. Taylor Swift will be arriving first at FedEx Field for two nights (July 10-11) to tour on her 2017 album “Reputation,” which brought out a darker side for the once pristine girl next door. Power couple Beyoncé and Jay-Z also make a two-night stop (July 27-28) at the Landover stadium, and fans scooped up tickets, excited to hear the couple’s catalogue of hits — and that was before they surprise dropped a collaboration album “Everything is Love” last month. Times and prices vary. — Hau Chu

Britney Spears at the Theater at MGM National Harbor , July 12-13

Whether you’re one of her fans who came of age in the ’90s, one of her fans who wasn’t alive in the ’90s or just a person who appreciates a sharply executed hip-snap-body-roll-hair-whip combo, since 2013, seeing Britney Spears live has required traveling to Las Vegas, where the pop demigod has packed a concert hall nightly. The “Toxic” singer’s summer tour is a chance to catch a version of that high-rolling show without boarding a plane: Expect theatrical smoke (choreographed, vocal, maybe literal) and songs, plucked from a 20-year career, that please the crowd, from the “ . . . Baby One More Time”-era glucose-spikers to her more recent trysts with EDM. 8 p.m. From $415. — Julie Bone

‘Dave’ at Arena Stage , July 13-Aug. 19

Naturally, the musical version of the Kevin Kline and Sigourney Weaver political rom-com “Dave” is making its world premiere in the capital. If you haven’t caught it on cable recently, the 1993 film revolved around an average guy who ends up standing in for the president (stranger things have happened), and then falls for the first lady. The production team’s credentials include Tony and Pulitzer Prize awards, so that bodes well for this “Dave” reboot debuting at Arena Stage. $76-$125. — Adele Chapin

Major League Baseball All-Star Game and FanFest , July 13-17

Washington is hosting baseball’s All-Star Game for the first time since 1969, and the hoopla around All-Star Weekend is as much of an attraction as the game (July 17) itself. The FanFest at the Walter E. Washington Convention Center features autograph sessions with Hall of Famers and members of the 2005 Nationals, interactive games and batting cages, and displays from the Hall of Fame. Elsewhere in the city, the Library of Congress showcases items from its collection in the “Baseball Americana” exhibition; and Yards Park’s Summer Riverfest on July 14 and 15 includes outdoor games, live music and a screening of “The Sandlot.” Fanfest $15-$35; other events free. — Fritz Hahn

District of Comedy festival , July 19-21

For the third year in a row the Kennedy Center is staging the District of Comedy festival, which celebrates all things comedy, including stand-up, sketch, improv, music and podcasts. Highlights include Virginia native Patton Oswalt; James Adomian breaking out his Bernie Sanders impression; “The Problem with Apu” director Hari Kondabolu doing stand-up; “Insecure’s” Amanda Seales; a series of Second City shows; and “RIOT!: Women in Comedy,” a showcase featuring cabaret comedian Bridget Everett, “2 Dope Queens’” Phoebe Robinson and former (and current) “Saturday Night Live” stars. Times and prices vary. — Rudi Greenberg

Artscape , July 20-22

Many festivals promise “something for everyone.” Baltimore’s annual Artscape — the country’s largest free arts festival — comes closest to delivering. The three-day gathering in the city’s Station North and Bolton Hill neighborhoods is a riot of originality. Wander through numerous installations and interactive works created by Baltimore artists and a marketplace with almost 150 vendors, and you’ll find a “Dance Camp” with performances by local pros; performances by the Baltimore Symphony Orchestra, experimental opera groups, indie rock and hip-hop acts; pop-up comedy and improv groups; fancifully decorated Art Cars and free movie screenings. The biggest draws are the evening concerts, with TLC (Friday) and Toots and the Maytalls (Saturday). Friday and Saturday from 11 a.m. to 9 p.m.; Sunday 11 a.m. to 7 p.m. Free. — F.H.

Lotus and Water Lily Festival at Kenilworth Aquatic Gardens , July 21-22

People come from all over the world to see this spectacular display of lotuses and lilies at Kenilworth Aquatic Gardens, but it’s surprisingly less known among locals. Even if you don’t care about flowers, you’re sure to be wowed by these blooms. Sacred lotuses stand on 3-foot-tall stems and sport blooms the size of dinner plates. You’ll also see lilypads big enough to surf on, not to mention wild birds, frogs and turtles — assuming you get there early enough, before the sun sends them into hiding. There’ll also be programs with animals, music and interactive projects for kids. 10 a.m. to 5 p.m. Free. — S.D.

SAAM Arcade , July 22

The Smithsonian American Art Museum’s Kogod Courtyard turns into the area’s largest arcade during this day-long festival. Get nostalgic playing vintage Donkey Kong or X-Men console games, or get a sneak peek at the next wave of games with previews from independent developers. More than 100 games will be available for free play throughout the afternoon. 11:30 a.m. to 7 p.m. Free. — F.H.

Blerdcon , July 27-29

This fledging convention at the Hyatt Regency Crystal City, now in its second year, is dedicated to all things geek, with an emphasis on the “black nerd” experience. You’ll find many typical con activities, including panels, gaming tournaments and a cosplay contest, all within the context of celebrating diversity. Four members of “Black Panther’s” Dora Milaje warriors are slated to appear, along with other actors, writers and experts in the blerd community. Blerdcon is also openly inclusive of those who sometimes find themselves invisible at mainstream cons, including the LGBTQ community, people with disabilities and people of color. After all, geek is a language that transcends all barriers. Times vary. Day passes, $15-$35; weekend pass, $50. Autograph and meet and greets cost extra. — Kristen Page-Kirby
