Pink Floyd - The Early Years 1971: Reverber/ation (2017) [Hi-Res]

Originally released as part of the mammoth 2016 rarities clearinghouse The Early Years 1965-1972, 1971 Reverber/Ation contains all the known unreleased music and video Pink Floyd recorded that year. The single CD contains a work-in-progress version of "Echoes" called "Nothing, Pt. 14," plus a BBC session from September. There's greater variety on the DVD/Blu-rays, which contain the quad mix of "Echoes"; a short film for German TV; performances in France, Austria, and Australia; an Ian Emes animation for "One of These Days"; a brief documentary called "24 Hours -- Bootleg Records"; and an interview with the band's album designer, Storm Thorgerson.
