Greatest! is the fourth
album by American singer-songwriter
Johnny Cash, released on
Sun Records on 12 January 1959 (see
1959 in music). It was Cash's third record on the label, which he had left the previous year to join
Columbia Records. By the time the album was released, Cash had already recorded
The Fabulous Johnny Cash, his first album with Columbia. This overlap would continue until 1964 with Sun releasing additional albums and singles of previously unreleased material in parallel with Cash's Columbia releases.
