Produced for the Classic Albums series, this thorough and thought-provoking study highlights a track-by-track dissection of the LP's master tapes (including the spoken-word passages that bookend the album), superbly interlaced with archival footage, early demo tapes, concert animations and latter-day acoustic performances by David Gilmour, Roger Waters and Richard Wright to demonstrate each track's contribution to the final mix--a sonic exploration that extends to the illuminating bonus features. Informative interviews abound (including Rolling Stone senior editor David Fricke), and much-deserved credit is given to saxophonist Dick Parry, solo vocalist Clare Torry and former Columbia Records chairman Bhaskar Menon, who fostered the album's US commercial success. For Floyd fans, musicians and studio technicians alike, this is a must-have addition to any DVD library. --Jeff Shannon
