This two-disc DVD collection of live performances by ’70s rock giants Led Zeppelin is terrific. Disc one sports an entire 1970 concert performance at Royal Albert Hall in London. The sound is stereo and full—John Paul Jones’ bass has booming depth, John Bonham’s drums span everything in-between, and Jimmy Page’s guitar buzzes at the top end. It’s remarkable how strong the young Robert Plant’s voice is here. Before he got into thinly veiled Janis Joplin impressions, Plant’s voice was full-throated and captivating. Several European TV appearances round out the first disc. The second disc highlights include a great, mostly acoustic 1975 performance from Earls Court (this sequence required the most restoration work, as it was captured on ancient 2-inch video tape), and a fairly fantastic show at Knebworth in 1979, mere months before Bonham’s death.
