I can't help with jazz, etc., but I can recommend Johnny Cash's four American Records albums with Rick Rubin: "American Recordings," "Unchained," "Solitary Man," and "The Man Comes Around." Each has incredible sonics, with Johnny's voice dead center and BIG and booming--as it damn well should be. Most of Johnny's records were pretty well recorded, but, to my ears, these sound the best. "The Man Comes Around," in particular, will send shivers up your spine. It was his last album before his death--and let's just say this: The man went out on TOP.
