Washington has sold out. Want evidence? Try going to a concert.  

Last weekend’s St. Vincent shows at the 9:30 Club sold out so quickly many people didn’t even feel like they had a chance to score a ticket. And while the folks at the 9:30 Club say they don’t keep track of their previous sell-outs, their upcoming schedule shows that if want to hear music there, even from acts not at the top of the charts, you’d best be organized. This Sunday’s Broken Bells show is sold out. The March 14 Dr. Dog show sold out, prompting a second show on March 15. The Drive-By Truckers have sold out their March 22 show. Grouplove has sold out three nights in a row, March 30, March 31 and April 1. The Kraftwerk 3-D Concert has sold out two shows on April 4.  

And it’s not just 9:30. At the Black Cat , Wednesday night’s Ex Hex show is sold out and low ticket alerts have been prompted by sales for Thursday’s Speedy Ortiz show and Friday’s We Were Promised Jetpacks show.  

Lesson? The first time you even think you want to see someone at one of the medium-sized venues, just buy the tickets, post haste.
