Bradford Cox a/k/a Atlas Sound (that’s him to the left) could’ve been a hypnotist in a prior life—if in doubt, stop by the Bell House, where he’ll put the audience in a trance with subdued fluorescent vocals layered over tamed, fraying guitars and electronic noise that bubbles to the surface like repressed memories of heartbreak and longing. If you’re seeking regression to simpler, sweeter times, the Postelles—who’ve imbued their tweeny-pop tunes with a healthy helping of Motown fire—kick off their Bowery Electric residency . .. and since this first night’s free, you won’t have to save up your milk money. Stories in High Fidelity, an evening of storytelling and performances at the Bowery Ballroom, features David Byrne and his kooky video/audio lecture on the connection between context and creativity. Finally, at the Highline Ballroom, the South African-styled choir Ladysmith Black Mambazo remind us that they’re still dancing and singing after 40-plus records. Beat that, Madonna.
