Part 1 of Jeff Plankenhorn at public radio program Live From The Divide in beautiful Bozeman, MT. Jeff Plankenhorn is a larger than life presence on stage. A big man with a kind smile and generous demeanor, he is often the bedrock that binds a host of talents into a moving whole. Then he picks up his slide, looks down in his lap and the joint starts hopping. Plankenhorn made his name in Austin as a preeminent guitar slinger, especially as a slide specialist.
