More concerned with the essence of a song than idiomatic limitations, vocalist Kate McGarry and guitarist Keith Ganz have managed to attract the attention of tomorrow’s jazz fans. Beyond their obvious affinity for swing, their eclectic repertoire ranging from Irving Berlin to The Cars, and her signature contralto convey a message with a crystal clarity that precludes the need for gimmick or effect. All that’s left is undeniably honest music that transcends the boundaries of age or genre.
