Classic Cash: Hall of Fame Series is the 74th album by the Americancountry singer Johnny Cash, released on Mercury Records in 1988 (see 1988 in music). It consists entirely of re-recordings of songs already associated with Cash from his Sun and Columbia days. The album has been both criticized and praised because of the use of several modern production techniques, including synthesizers, in an attempt to update and modernize Cash's earlier songs.[citation needed]
