In what basically amounts to a reissue of 1992's similarly titled Complete Mercury Sessions, Universal's Complete Mercury Recordings has improved upon the original by putting the songs in chronological order and including terrific liner notes by folk historian Mary Katherine Aldin. While both Flatt & Scruggs releases include the early classics "Foggy Mountain Breakdown," "Roll in My Sweet Baby's Arms," and "Salty Dog Blues," the extras on this release make it the one to own.
