Emerging out of the sound of the spring peepers that close her new album, Middle Cyclone, Neko Case and her five-piece band opened the night’s performance with "Maybe Sparrow." The stage was set in something out of a nature cartoon with trees painted on long banners and an owl overseeing it all. Behind them videos of cyclones, airplanes and anthropomorphic animals were projected on a screen. But the attention was clearly on Case, her stunning voice, as well as her solid backing band. She gave a full concert from Washington, D.C.’s 9:30 Club, which was webcast live on NPR.org.
