What do Billie Holiday and Lady Gaga have in common? What about Queen Latifah and rockabilly star Wanda Jackson? Well, besides gender and fame, their influence on a deeply sexist recording industry. The final presentation of the National Museum of Women in the Arts’ 25th anniversary season, “Women Who Rock: Vision, Passion, Power” traces the history of women in the music business beginning in the 1920s.

Seattle has Pike Place Market. New York has Chelsea Market. San Francisco has Ferry Plaza Market. Now, Union Market is poising itself to become D.C.’s equivalent. The food emporium, opening at 6th St. and Florida Ave. NE tomorrow, will feature 40 local artisans. Among the highlights: Rappahannock Oyster Company, Righteous Cheese, Peregrine, D.C. Empanadas, TaKorean, Red Apron Butchery, and a soda shop from mixologist Gina Chersevani called Buffalo & Bergen (although not all of them will be open on Day 1). To celebrate the opening, Union Market will be hosting its second annual DC Scoop ice cream competition and tasting from 1 to 4 p.m. on Sunday. Stop by for cold treats from Dolcezza Gelato, Sinplicity,Sweet Willows Creamery, Goodies Frozen Custard, and more. Y&H will be judging the competition, so stop by and say hi. Union Market, 1309 5th St. NE; unionmarketdc.com.

OH AND ALSO

“It’s a fucking party, is what it is!” is how Bob Mould recently described Copper Blue, his band Sugar’s 1992 debut, in an interview with music website The Quietus. “I love those songs, I love that record, and I love playing those songs.” That’s as good a reason as any to resurrect Sugar’s earthy indie-rock classic on its 20th anniversary. But Mould—an icon of the American underground for his role in Hüsker Dü in the 1980s—is still working on his legacy. He’s made muscular post-punk with various groups, forayed into electronic music, penned scripts for professional wrestling, and, in 2011, published a well-reviewed memoir that charted his growth from a closeted teenage punk to one of the out-and-proud DJs behind D.C.’s regular Blowoff dance parties.

Bob Mould performs at 7 p.m. Saturday at 9:30 Club, 815 V St. NW. $25. Blowoff starts at 11:30 p.m. $12. (202) 265-0930. 930.com.

Is one year long enough to make an impact? Definitely. What about one hour? Er, maybe. Celebrating one year online, Huffington Post D.C.—the local branch of Arianna Huffington’s news and pop-culture amoeba—is getting behind a variety show at the Kennedy Center’s Millennium Stage tonight. Like the aggregation-happy Huffington Post itself, the show cannibalizes from other sources: Host Brandon Wetherbee, an assistant editor at the website (and a former City Paper contributor) has long hosted his own variety show, “You, Me, Them, Everybody!” at various bars and spaces around town. The format is borrowed, too: Wetherbee writes a regular “Top 5” arts and entertainment feature for his employer. But besides that, this show’s lineup is all original, and (mostly) hyperlocal to boot.

Huffington Post D.C.’s Top 5 begins at 6 p.m. Sunday at the Kennedy Center Millennium Stage, 2700 F St. NW. Free. kennedy-center.org. (202) 467-4600.
