There was no mistaking the twang in Liz Brasher's voice, but her fiery set for 14 Inch Fringe on Thursday afternoon was driven by pure R&B fury. The Memphis native fronts a rare entity: a soul power trio. It was a lean, mean arrangement that still packed a punch even when Brasher traded her guitar for a tambourine, like she did on the sizzling finale. That was in no small part due to Brasher's voice, a bold, booming instrument that would have felt oversized in a venue far bigger than the Yeti storefront at which she performed. And it was fun stuff, as she mugged and smiled her way through the set. J.G.
