Simon Wilde is one of the scientists who found a tiny, four billion year old zircon in Australia. He brought it to his colleague Joe Skullan at the University of Wisconsin and they established that it’s the oldest object on earth. This inspired musician Roy Nathanson, so his group, Jazz Passengers, performed the “Rock Concert” in Madison, Wisconsin. Wilde, Skullan and Nathanson tell their story to Steve Paulson, and we hear excerpts from the concert recording.
