Don't judge Carrie Brownstein by that bummer of a Portlandia tour; Wild Flag is the best live band in the world right now. Their stuff — just one release so far, the self-titled debut that took the prize in City Paper 's Top 21 Albums of 2011 list — is brazen, loud and relentlessly ecstatic. Brownstein (ex-Sleater-Kinney) and Mary Timony (ex-Helium) strut and sweat and sprawl out all over the stage, giving glory to rock 'n' roll with the spasmodic, glossolaliac fervor of a sinner who keeps seeing the light. Only the good stuff can do that to you.

Tue., April 3, 9 p.m., $18-$20, with Hospitality and Blood Feathers, Trocadero, 1003 Arch St., 215-922-6888, thetroc.com.
