FRIDAY

BEER: The Black Squirrel (2427 18th Street NW) is having an Oskar Blues event today at 5:00 until close where the Adams Morgan bar is tapping a keg of Oskar Blues HGH (Home Grown Hops) along with other Oskar Blues beers, including Ten Fidy, Dales, Old Chub, and Gubna. According to bar owner Amy Bowman: “Our distributor says that this is the only keg of this specialty beer coming into the city (others have made it into the area), and it will only be brewed once.”

MUSIC: Tonight, the poetry of Hildegard von Bingen a 12th-century nun, is put to music by the group Anonymous 4 at the Heavenly Revelations concert at the Washington National Cathedral (3101 Wisconsin Avenue NW). This concert is the first in a series of events from the Folger Library meant to celebrate 1,000 years of women writers. A free pre-concert discussion takes place at 6:30 p.m. The concert starts at 8 p.m. Tickets: $30-$50.

MORE MUSIC: They serve us booze, sell us tickets, stamp our hands and make vegan lasagna, but some of the folks on the Black Cat (1811 14th Street NW) staff are musicians in their own right. We already knew that The Shirks, The Aquarium and The Max Levine Ensemble had Cat employees in their lineup but during The Workers Party at Black Cat; we’ll get to hear from some bands we haven’t heard from as much: Mean Season, Booze Riot, The Red Moon Preachers and Raindeer. $5, 9:00 p.m.

SATURDAY

WALKING TOUR: Historic Strolls is hosting “The Expedition” today, which they describe thusly: “See where the Star Spangled Banner was first sung in DC, and the location of America’s oldest working elevator. (Spoiler: it’s at Potbelly’s.) Find out what happened to Charles Wilkes specimens from his daring research voyages, the secret D.C. connection to the Empire State Building, where George Washington made a gamble and much, much more. The Expedition will make a daring ascent of Capitol Hill using skill and the world’s tiniest climbing rope. Sir Hilary will bring chocolate rewards for guests who dress as their favorite explorer. But you don’t need to come in costume to enjoy a walk through some spectacular scenery.” Meet at the Potbelly Restaurant on Indiana Avenue NW at noon; the tour costs $12 for adults, $6 for anyone under 16.

FIGHT: Elvis’ Birthday Fight Club, a 21-and-over performance, takes today with two shows: 8 p.m. and 11 p.m. at The Warehouse Theatre (1021 7th Street NW). Tickets are $16 in advance and $20 day of.

MUSIC: Dance for the Dying takes the Rock & Roll Hotel (1353 H Street NE) tonight at 9 p.m. ($10), the 9:30 Club (815 V Street NW) features an 11 a.m. matinee with Bach 2 Rock ($5) and Crash Boom Bang at 8 p.m. ($15) and the Black Cat has its usual Hellmouth Happy Hour at 7 p.m. and King Face at 9 p.m. ($15).

SUNDAY

STREET PARTY: January 6 is formally Three Kings Day, but Columbia Heights’ GALA Theatre will be celebrating today with song, dance, storytelling and yes, a procession including live animals. For the celebration, free tickets will be handed out outside the theatre starting at 12:30 p.m., show starts at 2 p.m. The procession will start at 1:30 p.m. on the corner of 14th Street and Park Road NW.

MUSIC: It was just over a year ago that 26-year old vegetable vendor Mohamed Bouazizi set himself on fire to protest government corruption in Tunisia. That single event is recognized as the seed that grew into the Arab Spring, a seminal moment in world history. On Sunday, Tunisian violinist Nidhal Jebali and American pianist Kimball Gallagher will play a free program in the Kennedy Center’s Terrace Theater featuring their own original compositions, as well as works by Franck, Paganini, and Jaloul Ayad, the Tunisian Minister of Finance, in commemoration of this event. 6 p.m.
