The Folsom Prison CD sounds excellent and is a remarkable example of a live performance by the Man in Black. I recently purchased Johnny Cash at San Quentin and was very disappointed. The sound is constricted and heavily compressed and this was the latest "remastered" version. "The Essential Johnny Cash Collection" is excellent. I'd purchase all the Rick Rubin CDs 1-4, I don't think there is a bad one and if you really want to complete this collection, buy the "Unearthed" collection.
