Led Zeppelin were one of the most influential and commercially successful rock bands of all time, formed in London in 1968 by Jimmy Page, Robert Plant, John Paul Jones and John Bonham. Their fusion of blues, hard rock, folk and psychedelia helped define the sound of 1970s rock. Albums including Led Zeppelin IV, Physical Graffiti and Houses of the Holy became landmarks, while tracks such as “Stairway to Heaven”, “Whole Lotta Love” and “Kashmir” remain iconic. The band sold hundreds of millions of records worldwide before disbanding in 1980 following Bonham’s death. They reunited for a celebrated 2007 concert at London’s O2 Arena
