In November 2016, Pink Floyd released a box set, "The Early Years 1965–1972", comprising outtakes, live recordings, remixes, and films from their early career. It was followed in December 2019 by "The Later Years", compiling Pink Floyd's work after Waters' departure. The set includes a remixed version of "A Momentary Lapse of Reason" with more contributions by Wright and Mason, and an expanded reissue of the live album "Delicate Sound of Thunder". In March 2021, Pink Floyd announced that their "Live at Knebworth 1990" performance, previously released as part of the "Later Years" box set, would be released in CD and vinyl on 30 April.
