Don Everly, whose divine harmony with sibling Phil Everly in the Everly Brothers helped shape the course of rock 'n' roll, died Saturday in Nashville at age 84. The brothers' official Instagram account confirmed his death early Sunday. "It is with great sadness that we regret to announce the passing of Isaac Donald Everly today," a post reads. "He leaves behind his wife Adela, mother Margaret, children Venetia, Stacy, Erin & Edan, grandchildren Arabella, Easan, Stirling, Eres, Lily & Esper." The Everly Brothers were inducted in the inaugural class of the Rock and Roll Hall of Fame in 1986. Classics such as “Bye Bye Love,” “Wake Up, Little Susie” and “All I Have To Do Is Dream” epitomize the vocal blend of Everly and his younger brother, Phil, who died in 2014 from complications of chronic obstructive pulmonary disease. As his brother’s tenor soared, Everly was the anchor, singing the main melody on the bulk of their songs. Their sound soon found a rapt audience with the release of “Bye Bye Love” in 1957 – and it ignited the imaginations of teenagers who would later become The Beatles, Bob Dylan and Simon & Garfunkel.
