Engaging documentary deftly profiles the "Technicolor Dream," a 14-hour concert─or "musical happening" as it was billed─that was a fundraising effort for the International Times newspaper and a celebration of the '60s underground movement. The event, held on April 29, 1967, at Alexandra Palace in London was headlined by a Syd Barrett-era Pink Floyd. This release features musical performances from the show, as well as then-and-now interviews with Roger Waters, Nick Mason, and others. 125 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital stereo; bonus footage; interviews.
