When Grace, Sophia and Hulda Quebe (pronounced kway-bee) take to a stage to play and sing their vintage-style three-part harmony, audiences are mesmerized. Add the swinging rhythm guitar of World Champion fiddler Joey McKenzie and the upright bass of Drew Phelps, and the Quebe Sisters Band becomes a force of nature.
