Known to country fans mainly as the act in which Skeeter Davis originally rose to fame, the Davis Sisters' career would have surely been much more influential and successful if tragedy hadn't derailed them just after their first hit. Although they only had one big single ("I Forgot More Than You'll Ever Know," in 1953), their outstanding close dual harmonies helped link the Appalachian harmonies of the Delmore Brothers with the more modern ones of subsequent acts like the Everlys. They were also among the earliest female country singing stars of the post-World War II era, and occasionally went into a boogie mode that foreshadowed the rockabilly movement by a year or two.
