1946 Billboard Magazine Ad

“‘Hillbilly Boogie” by the Delmore Brothers directly anticipated the development of rockabilly and, later, rock and roll. With their close-knit harmonies and their guitar playing, the Delmores influenced the Everly Brothers and countless other country, rockabilly and rock and roll artists.”
