Recorded between 1951 and 1966, the 52 tracks that make up Columbia/Legacy’s Foggy Mountain Gospel compilation represent not only a high point in the careers of Lester Flatt and Earl Scruggs, but a pinnacle for the bluegrass-gospel genre itself. The material, pulled from seven albums and a smattering of singles recorded during the duo’s Columbia heydays, was produced by longtime collaborator Don Law and features some of Nashville’s most legendary session players. – James Christopher Monger
