(RNN) - Phil Everly, one half of the group the Everly Brothers, has died.
Everly's wife told the Los Angeles Times he died of complications from chronic obstructive pulmonary disease, the result of years of smoking. He was 74.
"We are absolutely heartbroken," Patti Everly told the newspaper. "He fought long and hard."
The group was comprised of real-life brothers Phil Everly and Don Everly, the sons of entertainers.
The family moved to Nashville in 1955 and the brothers got jobs as songwriters. They signed their first record deal in 1957 and began pumping out hits that walked the line between pop, rock and country with signature tight harmonies.
The Everly Brothers were inducted into the Rock and Roll Hall of Fame in its very first class in 1986 and the Country Music Hall of Fame in 2001.
They received a Recording Academy Lifetime Achievement Award in 1997.
Some of their most iconic hits include Wake Up Little Susie, Cathy's Clown and All I Have to do is Dream, which was inducted into the Grammy Hall of Fame in 2004.
Their music influenced generations of artists, including the Beatles and the Byrds. More recently, Green Day's Billie Joe Armstrong and jazz artist Norah Jones recorded Foreverly, a cover album of the Everly Brothers' 1958 release Songs Our Daddy Taught Us.
"The duo's superb and flawless harmonies influenced some of music's most iconic acts," said Neil Portnow, president and CEO of The Recording Academy, in a statement. "Their profound impact on pop and rock music is still heard today, and will continue to live on in future generations."
