The Everly Brothers were an influential American rock duo known for their signature close-harmony singing and distinctive steel-string acoustic guitar sound. Brothers Don and Phil Everly blended rock and roll, country, and pop, helping to lay the foundation for country rock. Starting their careers as children performing with their family on radio, they broke through in 1957 with "Bye Bye Love," followed by hits like "Wake Up Little Susie," "All I Have to Do Is Dream," and "Cathy's Clown." Their innovative harmonies and songwriting deeply influenced groups such as the Beatles, the Beach Boys, and Simon and Garfunkel. Though their popularity in the US waned in the 1960s, they remained successful internationally and reunited in the 1980s after a brief split. The Everly Brothers are celebrated as pioneers of modern pop and rock and have been inducted into both the Rock and Roll and Country Music Halls of Fame. Their legacy continues to inspire musicians worldwide.
