You've probably heard-- or at least heard of-- Carl Orff's anthemic, and much adapted Carmina Burana. It's less likely that you've ever heard, or heard of, the multi-instrumental genius Sandy Bull, who covered Orff's masterpiece with a 5-string banjo in 1963 on his debut album, Fantasias For Guitar and Banjo. I met him at the Cafe Au Go Go a few years later and persuaded him to come play a show at my college on Long Island. He astounded me by being able to locate radio frequencies on my car dial that I didn't know existed. And by playing an oud, which I had never even heard of 'til then.
