I guess we just had our biggest snowstorm of the season this week, but spring is in the air (really!) and that means it’s time to get out of the house. The forecast calls for toasty highs in the 40s this weekend. Put on your flip-flops. There’s no shortage of concerts to pull you off the couch, too. On Thursday Gavin Russom’s latest weird disco project Crystal Ark makes its local debut at the Elbo Room, while DJ Jazzy Jeff brings another kind of old-school to the Shrine. On Friday nuanced blues singer Shemekia Copeland plays Space in Evanston, while Implodes and Night Terror play Chicago Underground Film Festival party at the Burlington. On Saturday Fifth House Ensemble makes its debut at the Museum of Contemporary Art with a terrific-looking program and the Hideout presents its annual South by Southwest send-off to raise travel funds for 11 local bands headed to Austin. Last but not least, among Sunday’s highlights is the return of Malian kora player Ballake Sissoko and French cellist Vincent Segal to the Old Town School and the great double bill of Deathfix and Brokeback at Schubas. After the jump you can read about four more great shows covered in this week’s Soundboard.
