LONDON -- Gregg Allman and John Paul White of The Civil Wars will share a stage for the first time for a gig during the Sundance London film and music festival.

The duo's performance will be coupled with the U.K. premiere of Greg "Freddy" Camalier’s music documentary Muscle Shoals during the second London-based edition of Robert Redford's festival.

Rock and Roll Hall of Famer Allman is a founding member of the Allman Brothers Band, whose hits include Whipping Post, Dreams and Melissa. He's also had a long career as a solo artist.

White was born and still lives in Muscle Shoals, Alabama, and released the album The Long Goodbye in 2008 before joining Joy Williams the following year to form The Civil Wars.

The duo won Grammy Awards in 2012 for best folk album and best country performance by a duo or group.

White said: "For musicians raised in the heart of the South, the Allman Brothers are gods. Count me among the worshipers. I'm honored immensely to be included in this project in any small way, and working with one of my heroes excites me to no end."

Camalier's doc Muscle Shoals details the musical history of Muscle Shoals, an unheralded gold mine of American music.

At the heart of Muscle Shoals is Rick Hall, who overcame hardship and ended up enticing talent such as Aretha Franklin and Wilson Pickett to the town to record at the studios.

Bob Dylan, the Rolling Stones, the Staples Singers, the Allman Brothers Band, Lynyrd Skynyrd and Simon and Garfunkel all followed suit.

The second Sundance London runs April 25-28, playing host to international and U.K. premieres of U.S. independent films fresh from the 2013 Sundance Film Festival in Park City earlier this year.
