Legacy Recordings is an American record label that is a division of Sony Music. Formed in 1990 after Sony's acquiring of CBS Records, Legacy handles the archives of Sony Music-owned labels Columbia Records, Epic Records, RCA Records, RCA Records Nashville, J Records, Windham Hill Records, Arista, LaFace, Jive, Buddah Records, and Philadelphia International Records. It also handles the catalog of recordings produced by Phil Spector. The Essential series are one-to-two disc compilations of an artist's extensive catalog. On occasion, albums in this series would have a limited edition third disc (Labeled Essential 3.0), or revised to include an artist's newer work (for example The Essential Bob Dylan). As of 2015, several volumes in the Essential series are also available on Vinyl LP.
