"Rock'n'roll's greatest fraternal duo: Few voices blended as seamlessly as Don and Phil Everly's. By layering their soaring, bluegrass-inflected harmonies over rhythm and blues instrumentation, the Kentucky natives invented a wholly original sound in the 1950s. Paul McCartney credited them as "the biggest influence on John and me." Curated by Tom Petty's daughter Adria with Everly family help, this set collects hits and deep cuts. Covers include tunes by Jimmy Reed, Chuck Berry, Johnny Cash and frequent contributor Boudleaux Bryant, while over half the selections serve to remind that the brothers were top-shelf songwriters".
