The Ultrasonic Duo is a popular original and variety act from La Crosse Wisconsin featuring Don D. Harvey and Greg Grokowsky. Known for smooth strong vocals and tight harmonies, the duo can sound like a laid back vocal group or a high energy rock band. While they have never been tied to one particular style of music, they have been referred to as both traditional and contemporary. One description calls them an eclectic hybrid of Country Folk, Acoustic Electric Rock, and Bluegrass. Their new CD In The Moonlight has just been released with new material written by the award winning songwriter Don D. Harvey. His song “Technology Blues” won Song of the Year at the KVAMA (Larryfest) Songwriting Contest in 200
