2015 reissue. By 1975 no one was bigger or heavier than Zeppelin. America was punch drunk after the quadruple whammy of their first four albums, each supported by tours that went from scene-stealing support slots to stadium-filling three-hour marathons, almost overnight. Even the slightly below average (ie: one or two sub-par tracks) Houses Of The Holy (1973) hadn't dented their reputation one jot. The world, and its attendant pleasures, was theirs for the taking. At this point most modern bands would take 5 years off and forget each others' names. What did Robert, Jimmy, John Paul and Bonzo do? Produced a double album that some still hold to be their best of all time.
