For the minimalists who couldn’t get enough John Cage during the September celebration of the composer’s centennial, or were disappointed by the dining options near the National Gallery of Art, tonight’s concert at the Atlas Performing Arts Center offers the chance to eat, drink, and be wowed by the avant-garde. Performing tonight are yMusic (shown) and the American Classical Music Ensemble (ACME), two New York–based contemporary classical groups specializing in genre-bending collaborations. Read more >>> yMusic and ACME perform at 9:30 p.m. at Atlas Performing Arts Center, 1333 H St. N.E. Free. Reservations required. (202) 399-7993. atlasarts.org. (Rebecca J. Ritzel)


We hope you don’t have pop-up fatigue yet, because tomorrow an up-and-coming food concept called Chaya will be hosting a taco pop-up at HR-57 on H Street NE from 1-4 p.m. The prix fixe $20 meal will feature vegetarian fare and includes Chocolate City Beer. Chaya, created by Bettina Stern and Suzanne Simon, was a finalist for StartUp Kitchen, a “food incubator” developed by Think Local First DC and NURISH: The Center for a Creative Culinary Economy. Food entrepreneurs presented their concepts to a panel of food industry vets, who selected a winner (Chaya) to test drive its business plan with the help of restaurant mentors. Alongside the pop-up meal will be the first StartUp Market, where other local food and craft entrepreneurs will sell their products. Tickets for the market are $3 in advance and $5 at the door and can be purchased hereHR-57, 1007 H St. NE; startupmarket.eventbrite.com. (Jessica Sidman)


This afternoon: Watch a tree explode on the National Mall.

Tonight: A new “webumentary” on D.C.’s Latino mural-making scene, Muralismo DC, premieres tonight at the Art + Media House in Columbia Heights. A panel discussion with light refreshments follows. Take a look at the trailer and RSVP to the screening at info@holacultura.com. 7 p.m. at 3035 15th St. NW. Free.

Saturday: There are just some things that get people into the holiday spirit: baking gingerbread men, singing Christmas songs, watching A Charlie Brown Christmas. But for a certain sect of public-radio listeners, it never really feels like December until they hear David Sedaris read from “The Santaland Diaries.” Fortunately, Actor Joe Brack brings his version to Fort Fringe starting tonight.

Saturday: American University’s radio station is hosting its final show of the semester, and it smartly chose to end the year with one of D.C.’s most creative, bizarre bands, Heavy Breathing. (To get a sense of the band’s freaky aesthetic, watch the NSFW video for its song “U the One I Want.”) The ensemble performs with local “aquawave”/soul-pop combo Misun. More info on Facebook7:30 p.m. at the Kay Spiritual Life Center at American University, 4400 Massachusetts Ave. NW. Free.

Sunday: Before you seriously consider wearing pajamas outside of your home on Sunday, weigh the costs and rewards. Yes, you will look like an escapee from St. Elizabeths. On the other hand, if you happen to be shopping in Maryland’s wind-chime capital, you’ll get discounts! Read more >>> (Ally Schweitzer)
