Rock star. Whatever that term means to you, chances are it owes a debt to Led Zeppelin. No one before or since has lived the dream quite like Jimmy Page, Robert Plant, John Paul Jones, and John Bonham. In Led Zeppelin, Bob Spitz takes their full measure, separating myth from reality with his trademark connoisseurship and storytelling flair. From the opening notes of their first album, the band announced itself as something different, a collision of grand artistic ambition and brute primal force, of English folk music and African American blues. Spitz's account of their artistic journey, amid the fascinating ecosystem of popular music, is irresistible. But the music is only part of the legend: Led Zeppelin is also the story of how the sixties became the seventies, of how innocence became decadence, of how rock took over. Led Zeppelin wasn't the first band to let loose on the road, but as with everything else, they took it to an entirely new level. Not all the legends are true, but in Spitz's careful accounting, what is true is astonishing and sometimes disturbing. Led Zeppelin gave no quarter, and neither has Bob Spitz. Led Zeppelin is the long-awaited full reckoning the band richly deserves.
