Forty years since their formation in a grubby Chinatown basement comes the first truly definitive biography of the world's most legendary rock band - Led Zeppelin.They were 'the last great band of the sixties; the first great band of the seventies'; they rose, somewhat unpromisingly, from the ashes of the Yardbirds to become one of the biggest-selling rock bands of all time. Mick Wall, respected rock writer and former confidant of both Page and Plant, unflinchingly tells the story of the band that wrote the rulebook for on-the-road excess - and eventually paid the price for it, with disaster, drug addiction and death. When Giants Walked the Earth reveals for the first time the true extent of band leader Jimmy Page's longstanding interest in the occult, and goes behind the scenes to expose the truth behind their much-hyped yet spectacularly contrived comeback at London's O2 arena last year, and how Jimmy Page plans to bring the band back permanently - if only his former protege, now part-time nemesis, Robert Plant will allow him to. And Wall also recounts, in a series of flashbacks, the life stories of the five individuals that made the dream of Led Zeppelin into an even more incredible and hard-to-swallow reality: Page, Plant, John Paul Jones, John Bonham, and their infamous manager, Peter Grant.Above all, a book that tells the full, shocking story of Led Zeppelin from the inside, written by someone who has known Jimmy Page for over twenty years, When Giants Walked the Earth is the culmination of several years research. It is based not just on the individual interviews with every member of the band that author Mick Wall has conducted over the years - as well as those who knew and worked with them - but on the insight that only thirty years working in the music business alongside its biggest artists can bring.
