Formed by the unlikely alliance of two ace London studio musicians and two bar-band bumpkins, Led Zeppelin went on to create the template for the marauding modern rock 'n' roll band. Often described as heavy, any true fan will tell you that the band's nine studio albums and 81 tracks thereon are actually a complex amalgam of blues, psychedelia, rock, folk, and country that reveal the influences of Led Zeppelin's four members. Veteran music journalist Martin Popoff picks apart each of these 81 tracks in exquisite detail, and for the first time ever, you can come along for the ride. Popoff analyzes the circumstances that led to their creation, the recording processes, the historical contexts, and more. Included as a special bonus, he also offers an introductory essay on each of the band's nine studio albums, and sidebar features that explore influences on the band as well as song details, such as running time, instruments played, engineers, and studios.
