Red was enthusing about these recently released live recordings of Woody Guthrie . The first ever example of such a thing - details here. Apparently recorded by a fan it's an interesting document of a show in Newark New Jersey in 1949 complete with on-stage banter and so on. If you don't know Guthrie's work than watch this little film. I haven't heard these recordings yet but I imagine it might be a good place to start an appreciation.
