Up there with the likes of The Beatles and The Rolling Stones, Led Zeppelin are one of a handful of rock bands whose influence is so colossal that it’s hard to put into perspective. With album sales topping 200 million and a guaranteed high place in any music poll, there aren’t any other hard rock acts that can match the group in terms of sales, influence or enduring popularity. Formed in 1968 by guitarist Jimmy Page, vocalist Robert Plant, bassist John Paul Jones and drummer John Bonham, the quartet was quickly signed to Atlantic Records. After touring the USA as support to Vanilla Fudge, Led Zeppelin’s self-titled debut saw a release. It was a mesmeric blend of heavy riffs, piercing vocals, and classic blues rock that was matched on its follow-up, Led Zeppelin II. A more reflective, acoustic subtlety was revealed on Led Zeppellin III, and subsequent releases saw the band incorporating elements of rockabilly, funk and world music. Things started to go wrong, however, with Plant being badly injured in a car crash and, in 1980, Bonham dying after a drinking binge. Following his death, the other three decided to call time on the band. 2007 saw the trio reunite, with John’s son Jason Bonham on drums, for a memorial concert for Ahmet Ertegun.
