Blisspop Disco Fest at 9:30 Club and U Street Music Hall: D.C. disco fans finally have a festival to call their own, a two-day celebration of upbeat dance grooves at the 9:30 Club and U Street Music Hall. Blisspop, over Labor Day weekend, is inspired by disco’s past and future: EDM pioneer Giorgio Moroder, whose production of seminal tracks like Donna Summer’s “I Feel Love” earned him the nickname “Father of Disco,” and German house DJ and producer Claptone take turns headlining the 9:30 Club. Afterward, the party shifts to the dance floor at U Street Music Hall, where featured DJs include London-based duo Horse Meat Disco, Nancy Whang of LCD Soundsystem and the New York synth-pop duo Holy Ghost. Through Saturday. 8 and 10 p.m. $15-$50.
‘South Pacific’ at Olney Theatre: The Pulitzer Prize-winning 1949 Rodgers and Hammerstein musical, featuring such classics as “Some Enchanted Evening” and “Bali Ha’i,” gets a reboot starring Jessica Lauren Ball (“Guys and Dolls”). Set during World War II, the story examines racism and prejudice as romance heats up between an American nurse and French expat stationed in a remote South Pacific island. Through Oct. 7. $42-$84.
Greenbelt Labor Day Festival: The 64-year-old Greenbelt Labor Day Festival retains the feeling of an traditional community fair, with carnival rides and games; live oldies and soul bands; a used book sale; and activities including roller skating and table tennis, capped with a Monday parade through the community. Through Monday. Free.
Maren Morris at Jiffy Lube Live: When life on the Nashville songwriting circuit wasn’t going as smoothly as Maren Morris expected, she decided to take matters into her own hands and go solo. Her 2015 debut single, “My Church,” was a nostalgic ode to cruising the highway with the windows rolled down and the music cranked up. It racked up a million streams within that week and, less than two years later, a Grammy. The song was born in the country music tradition with its bluesy drawl and down home themes, but Morris has many weapons to pull. Her 2016 debut album, “Hero,” dabbled in catchy Top-40 styles, soul and even a bit of reggae. But her biggest hit? That would be “The Middle,” a glossy electro-pop track made with producer Zedd that’s amassed nearly half a billion streams on Spotify. Morris, as she charts her own country crossover trajectory, is proof that, sometimes, it pays to bet on yourself. 7 p.m. $20-$130.65.
