Friday: The eight-screen Angelika Theater coming to the Union Market neighborhood isn’t scheduled to open until 2015, but the Angelika Pop-Up at Union Market, a three-screen “micro cinema” launching Friday in a Northeast warehouse space, should keep you entertained until then. Films shown during opening weekend will include the 20th-anniversary edition of Patrice Chereau’s “Queen Margot” and “Supermensch: The Legend of Shep Gordon,” the directorial debut of actor Mike Myers.

Friday-Saturday: Grammy Award-winning trumpeter Nicholas Payton’s explorations of what he calls BAM, or black American music, have included his own takes on Miles Davis’s funk and the classic sounds of New Orleans brass, unburdened by the usual trappings of the genre. A 2012 visit to Bohemian Caverns resulted in a blistering live album; let’s hope Payton can bottle that lightning when his Nicholas Payton Trio hits Blues Alley for a four-show, two-night gig.

Saturday: Willie Nelson turned 81 in late April, and if the Red Headed Stranger doesn’t quite have the same verve he had a few decades ago, he shows no signs of slowing down: He hits Merriweather Post Pavilion in the midst of a marathon tour with bluegrass star Alison Krauss and Union Station and Grammy Award-winning newcomer Kacey Musgraves. Willie's new album, “Band of Brothers,” comes out Tuesday.

Saturday:The Union BBQ might sound like an event for meat-loving foodies, but it’s actually the first day-long festival curated by the team behind U Street Music Hall. The indoor-outdoor event features DJ sets from Jamie xx, Animal Collective, Nadastrom and Tittsworth on two stages from noon to midnight. And yes, there will be barbecue (and more) to eat from a handful of vendors, including DCity Smokehouse.

Saturday: A slice of the bayou in Northern Virginia, Wolf Trap’s Louisiana Swamp Romp features one of its brassiest lineups in its 25 years. Big Sam’s Funky Nation, led by former Dirty Dozen Brass Band trombonist “Big Sam” Williams, and the Stooges Brass Band hold down the funky end of jazz, while BeauSoleil avec Michael Doucet represents the zydeco side of the state.

Sunday: Singer and Le Cordon Bleu-trained chef Kelis is serving up a lot more than a "Milkshake" these days. The seminal hit from 2003's "Tasty" is still an R&B/pop classic, but the New York native has moved on to heartier fare: "Biscuits n' Gravy," "Jerk Ribs" and "Cobbler" are among the soul-nourishing tracks on her new album, "Food." Kelis is also pushing a new show on the Cooking Channel, "Saucy and Sweet." Doors open at 7 p.m. for Kelis's show at the 9:30 Club.

Sunday: It's your last chance to see Rineke Dijkstra’s multi-channel video installation, “The Krazyhouse,” at the Corcoran Gallery of Art. The Dutch photographer’s 2009 work takes its name from the Liverpool nightclub where he filmed five young people -- identified only as Megan, Simon, Nikky, Philip and Dee -- dancing, and sometimes singing, along to their favorite club hits. The piece highlights a sense of self-consciousness that is both brazenly theatrical and more than slightly awkward.
