This last great Led Zeppelin album, is -- like most double LPs of the era -- a bloated beast. But its self-indulgent swagger is the very thing that makes it so much fun -- and one of the heaviest records of the 1970s. Powered by John Paul Jones' jittery clavinet, "Trampled Under Foot" is viking funk; "In My Time of Dying" is eleven minutes of slow-blues lava. The sprawl of Graffiti also let Jimmy Page and Robert Plant bring Zeppelin's less obvious gifts -- English folk and hillbilly romp -- out from behind the wall of amps. Plant would later cite the mighty Arab-influenced march "Kashmir" as one of Zeppelin's greatest achievements. (Rolling Stone)
