RIP Phil Everly

Phil Everly, who with his brother Don made up the most revered vocal duo of the rock-music era — their exquisite harmonies profoundly influencing the Beatles, the Beach Boys, the Byrds and countless younger rock, folk and country singers — died Friday in Burbank, Calif., of complications from chronic obstructive pulmonary disease, his wife, Patti Everly, said. He was 74.
