There are certain things about modern country music that tend to, well, rub some of us the wrong way. That is why, when an artist like Carlile emerges to make country palatable for the rest of us, it comes as a relief. With singles like “The Story” and her recent “Wherever Is Your Heart,” she offers the nostalgia and comforting melodies about your childhood sweetheart, with none of the ham-fisted insensitivity. She appears in a special acoustic, solo appearance at Sound Board.
