Led Zeppelin's blend of rock and heavy metal with other genres of music such as blues, soul, folk, pop, Indian and Celtic ranks them as one of the all-time greatest bands whose influence is still felt today. Taking a chronological look at their career, "Led Zeppelin Revealed" takes the reader from the heady days in 1968 when they first brought their unique sound to a worldwide audience, through the early 1970s when they were billed as the 'biggest band in the world' and to 1980s when they became household names on both sides of the Atlantic.
