Jonny Cash

As others have mentioned, the collaborations with Rick Rubin are all outstanding, both musically and technically. Given that you like the cover of "One", I'd strongly recommend American Recordings II: Unchained and then III: Solitary Man, which has One on it. These are the most lively of his later works. The final album is fantastic, as well, but you can really hear the struggle in Cash's voice.

Thanks. I thought about that one, too. I just got "At Folsom Prison" and I have to say, that is one of those rare discs, I listened from the beginning until the end without getting up. His voice alone is great, his guitar players are excellent and with June Carter there is something special going on, don't know what, but it's very impressing.
