The Delmore Brothers are not nearly as well-known as such early country giants as the Carter Family, Jimmie Rodgers, Bob Wills, and Hank Williams. The reasons for this, upon close inspection of their work, are not readily apparent. They were one of the greatest early country harmonizers, drawing from both gospel and Appalachian folk. They were skilled songwriters, penning literally hundreds of songs, many of which have proven to be durable. Most important, they were among the few early traditional country acts to change with the times, and pioneer some of those changes. Their recordings from the latter half of the 1940s married traditional country to boogie beats and bluesy riffs. In this respect they laid a foundation for rockabilly and early rock & roll, and rate among the most important white progenitors of those forms.
