Metallica's 1987 video debut Cliff 'Em All pays tribute to their original bassist Cliff Burton, who died in 1986 when the band's tour bus crashed in Sweden. Footage of home movies and concerts, personal photos, and unused television footage combine to paint a portrait of Metallica's early years and how important Burton was to the band's sound and identity. Though the DVD is lacking in special features, Cliff 'Em All is worthwhile for Metallica fans, particularly those into Master of Puppets and previous releases.
