During the 1940s, the Fairfield Four were among the top-ranked gospel quartets, along with the Dixie Hummingbirds, Five Blind Boys, and Soul Stirrers. Originally a gospel duet created in the early '20s by the pastor of Fairfield Baptist Church in Nashville to occupy his sons, Harry and Rufus Carrethers, they became a gospel trio with the addition of John Battle. The group was transformed into a jubilee quartet by the '30s and began the first of numerous personnel changes. They recorded for RCA Victor and Columbia during the decade and were known for their reinterpretations of standard hymns, featuring bright, close baritone and tenor harmonies. When the Fairfield Four sang, they utilized the full extent of their voices, moving easily from deep, rolling basslines to the staccato upper peaks of the tenor range, all executed with precise, intricate harmonies and ever-shifting leads.
