The documentary celebrating the Eagles’ 40th anniversary will premiere next month at the 2013 Sundance Film Festival. ‘History of the Eagles Part 1,’ that documents the early history of the band, will get its debut screening on January 19th at the Eccles Theater in Park City, Utah.

The rock-doc will trace the group’s story from the band’s formation in the early 1970’s to their initial breakup in 1980. All former and current band members, and many friends and musical associates, were interviewed for the documentary. The movie was directed by Alison Ellwood and produced by Alex Gibney, who won a Best Documentary Feature Oscar in 2008 for his work on ‘Taxi to the Dark Side.’

Eagles singer/guitarist Glenn Frey said in a statement: “For the last five years, and intensely this past year, we have been putting together this document of our history with Alex and Alison. We’re all very pleased with the progress so far, and are excited to see the finished product at Sundance.”

Guitarist Joe Walsh recently discussed his favorite period of the band’s history that the movie covered with ABC News Radio, talking fondly about his early days with the group, following the release of ‘Hotel California,’ when the Eagles “were in a huge creative phase.”

Walsh said, “All kinds of music got made in those days that’s still around today. And to have been part of that chemistry and camaraderie, and that energy…is something that not all musicians get a chance to experience…Riding that wave, shall we say, was nothing but wonderful memories.”

Former Eagles guitarist Don Felder, who sued the group after being fired back in 2001, also talked with ABC News Radio about his involvement in the film. “I got a call from my attorney who had heard from their attorney, and they had asked me to be involved in the documentary. And I thought it was only appropriate, after all the years and all the work that we had done together, that I went in and offered my appearance in the documentary. So we filmed for a day an interview that will be in the documentary.”
