Pink Floyd has released another video as a prelude to the upcoming The Early Years 1965-1972 box set.

The video is a remixed version of the track "Childhood's End."

The black-and-white video features vintage footage of the band, edited and mixed with footage of protesters from the era.

The song was taken from the band's Obscured By Clouds album, with the remix created by Andy Jackson and Damon Iddins.

The release of the "Childhood's End" video follows the August release of "Grantchester," taken off Ummagumma.

Both are a part of the massive 27-disc box set, which contains nearly 12 hours of audio and 14 hours of video.

The Early Yearsbox set is due in stores November 11.

Several other Pink Floyd albums are also scheduled for reissue this year.
