The bill for next month's Everly Brothers tribute is starting to take shape.
Graham Nash, Vince Gill and Emmylou Harris are among the performers set to pay tribute to the group.
The Rock and Roll of Fame announced Wednesday that Peter Asher, Shelby Lynne and the Secret Sisters will also perform at the Oct. 25 event at PlayhouseSquare's State Theatre in Cleveland.
Phil Everly died from chronic obstructive pulmonary disease earlier this year. Surviving member Don Everly will attend.
Singer Rodney Crowell will be the musical director for the concert, which will take place during the Rock Hall's 19th annual "Music Masters" series.
More performers will be announced at a later date. Tickets go on sale Sept. 10 for Rock Hall members.
The Everly Brothers were inducted into the Rock Hall in 1986 and the Country Music Hall of Fame in 2001.
The Everly Brothers helped draw the blueprint of rock 'n' roll in the late 1950s and 1960s with a high harmony that captured the yearning and angst of a nation of teenagers. They were behind the songs "Wake Up Little Susie" and "Bye Bye Love."
