Acquired wisdom has always put ÊSgt. PepperÊ at the head of the class but it was ÊRevolverÊ that truly signaled The Beatles' sea change from a functional band to a studio-based ensemble. These changes began before ÊRubber SoulÊ but came to fruition on ÊRevolverÊ which took an astonishing 300 hours to produce far more than any rock record before it.ÞThe making of ÊRevolverÊ ä hunkered down in Abbey Road with George Martin ä is in itself a great Beatles story but would be nothing if the results weren't so impactful. More than even ÊSgt. PepperÊ and ÊPet SoundsÊ ÊRevolverÊ fed directly into the rock 'n' roll zeitgeist and its influence could be heard everywhere: from the psychedelic San Francisco sound (Jefferson Airplane Grateful Dead); to the first wave of post-blues hard rock (Sabbath Zeppelin); through movie soundtracks and pretty much everything that followed it ä including every generation of guitar-based pop music and even heavy metal. More than any record before or after ÊRevolverÊ was the game-changer and this is finally the detailed telling of its storied recording and enormous impact.
