Blues and soul singer John Nemeth relocated to Memphis recently, and he's made fast friends. A former Boisean, Nemeth has a new album, "Memphis Grease," recorded with veteran Memphis act The Bo-Keys. And now they're touring as his backing band. Consider this: The Bo-Keys have backed acts ranging from Al Green to The Bar-Kays. Combined with Nemeth's smoldering harmonica chops and huge voice, this is the sort of Memphis grease that should start an onstage musical fire.
