Folk music seems simple, and many pretenders pull into town with little more than a presentable voice and a handful of beginner guitar chords. Much more infrequently, performers come along with basically the same constituent parts but through the sheer force of their artistry and integrity are able to use these simple elements to communicate whole lifetimes of experience. Such a performer is youthful Kate Rusby, who sings with the focus and depth one usually associates with the graceful compensations of age. Her crystal-clear voice (reminiscent in turns of Linda Thompson and Sandy Denny) rings out from the first cut. Rusby's assured delivery is dappled with small, unmasked idiosyncrasies that add emotional immediacy. Meanwhile, the all-acoustic presentation is inventive but never slick or overwhelming. Hourglass announces an important new light in the traditional British folk scene. --Anthony Bonet
