If you believe the rumblings in the underground, the next big retro craze is going to be '80s hardcore. Assuming that indeed comes to pass, Grant Hart might finally be recognized for what he is: one of the most important figures in the history of the American underground. Back when punk rock was a calling, not a career opportunity, Hart practically wrote the book on hard-candied punk with Hüsker Dü, a seminal outfit that proved it's sometimes okay when the drummer sings. When the Minneapolis trio imploded, he went on to form Nova Mob, switching to guitar and reinventing himself as a prog-fixated folk-punk with an occasional taste for rock opera. These days Hart is going it alone, but he's got no shortage of material to draw on from his back catalogue. Head to the Lamplighter on Tuesday (May 24) and hope like hell he plays "The Girl Who Lives on Heaven Hill".
