MIRANDA LAMBERT: Miranda Lambert looks a bit like Sarah Michelle Gellar on “Buffy the Vampire Slayer.” The 23-year-old Texan, a “Nashville Star” finalist, is forging a path rather like the Slayer’s, armed with a guitar instead of a wooden stake. Her songs of female empowerment and small-town wild-child fun have marked her as one of today’s most promising country ingénues. This dust-kicker’s more like a superheroine.
