The Crested Butte Music Festival is underway, and when we saw the schedule, one guest artist in particular caught our eye. He’s Rob Schwimmer, one of the world’s few professional theremin players. The theremin is often used to make eerie sounds, like in sci-fi movies. Schwimmer believes the theremin can do more than that -- even be beautiful. He speaks to Ryan Warner.
