93. Johnny Cash, 'Unearthed'
More brilliance from the bottomless musical vaults of Johnny Cash. Released just two months after Cash's death in 2003, this box set collects rarities and alternative takes from Cash's American Recordings albums helmed by Rick Rubin – parlor ballads, country classics, Bob Marley songs – and adds a bonus disc of gospel and spiritual songs. It's not just the definitive record of one of music's greatest late-career comebacks. It's a piece for the time capsule: a slice of American culture as monumental, and as enduring, as Mt. Rushmore.
