Even though the Everly Brothers had a great deal of success, especially in their early years, I still don't think that their importance is fully appreciated by modern rock fans. Born in Kentucky and into a family of musicians, they became famous with a string of big hits starting with 1957's "Bye Bye Love" and which continued to about 1965. They had multiple ups and downs along the way, including a split that lasted about ten years, but when they did perform their consistency was remarkable, and those early hits still sound amazing. Their influence as vocalists is easy to hear when you listen to the Beatles, the Beach Boys, E.L.O. or Queen - in fact any band that features harmony singing. Their comeback album, EB 84, was either vastly underappreciated (Robert Christgau gave it a C+, for example) or overlooked, which I've never been able to understand, because I hear it as brilliant. It features three splendid originals by Don Everly, as well as great songs written specifically for them by Paul McCartney ("On the Wings of a Nightingale": http://www.youtube.com/watch?v=h_c5BsTfI4g&feature=related) and Jeff Lynne ("The Story of Me": http://www.youtube.com/watch?v=PnyORL72xNc), among many other great tracks. You have to hear it.
