Explosively constructed around Robert Plant's howling vocals and Jimmy Page's demonic electric guitar, Led Zeppelin's pioneering heavy style laid the groundwork for the entire metal genre, making them one of the most influential bands of all time. Jimmy Page started out playing bass guitar with the Yardbirds, soon switching to lead guitar and recruiting Robert Plant, John Bonham and John Paul Jones as the New Yardbirds to fulfil outstanding dates after the Yardbirds split. As Led Zeppelin, their thunderous live shows and trailblazing albums attracted a fanatical following and by the mid-1970s they were the biggest band in the world, repeatedly breaking concert attendance records. Led Zeppelin 1V - including the iconic track Stairway To Heaven - has sold over 37m. Symbolising rock'n'roll excess, their career came to a shocking halt when drummer John Bonham died after choking on his own vomit in 1980. A one-off benefit show reunion in 2007 (with Bonham's son Jason on drums) fuelled speculation of a permanent comeback which hasn't materialised.
