When's the last time you heard a rock band singing about rabbis "sheppin' nachas" (translation: doling out pride) or parents kickin "tuchas?" Uh, never? Well, now there's a band on the scene to fill that void. They're called Blue Fringe, and they're a group of Orthodox 20-somethings who travel the U.S. playing catchy rock/pop music to packed shows. Think Oasis meets . . .well, an orthodox band.
