Collectors will want this compilation of Emmylou’s early work for the inclusion of a duet with Johnny Cash on “Old Rugged Cross”. Techno-buffs will want it for the crystalline 5:1 surround sound, remixed for DVD-A format by Brian Ahern, who produced 11 albums for Harris between 1975 and ’83. The rest of us can simply enjoy a fine selection that places such classics as “Boulder To Birmingham” and “Pancho And Lefty” alongside less celebrated gems like “The Last Cheater’s Waltz”.
