Howard Levy is a freak of nature. Is there anybody else on the face of the planet who can play chromatically (half-steps) on a diatonic (whole-step) harmonica like he does? If there is, I don't know about them. Howard's remarkable technique is probably the biggest physical innovation on any instrument since bottleneck slide guitar or the plunger over the trumpet bell. For now, his discovery that "all the notes" do in fact live inside the diatonic harmonica remains largely unsung.
