According to The Hollywood Reporter, Jimi Hendrix's closing performance at Woodstock on Aug. 18, 1969, is arguably one of the most iconic moments in rock history, but it has never been commercially available in its entirety. That will change on Sept. 13, when Universal Music and Experience Hendrix release the DVD Jimi Hendrix -- Live at Woodstock.

The project comes out a day earlier in the U.K. The double-disc set captures one of Hendrix's only performances with an extended backing band, dubbed Gypsy Sun and Rainbows. Longtime Hendrix engineer Eddie Kramer supervised a new audio mix in both 5.1 and 2.0 stereo sound. Bonus features include The Road to Woodstock documentary, a contemporaneous press conference and A Second Look, which blends black-and-white video footage with color clips from alternate angles.

More than 35 years later, Woodstock is still a high point for Gypsy Sun and Rainbows (and later, Band of Gypsies) bassist Billy Cox. "We had a house in Woodstock for maybe 30 days, and then the Woodstock Festival finally came up," he recalls to Billbord.com. "We worked, practiced and rehearsed very diligently for that. And the day finally came when we [played], and it was kind of a relief off our minds. We really did it as a group -- we were on stage for close to two hours."
