“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. (He also briefly wrote a column, Ask Bob, for Washington City Paper.) Tonight’s show will have its own memoiristic flavor: After Mould’s band finishes playing Copper Blue, they’ll play his newest LP, the pummeling and tuneful Silver Age. Make sure you stick around afterward for this month’s edition of Blowoff. Two great albums and a dance night: That’s three fucking parties for the price of two.

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