How a psychedelic experiment became the world's loudest rock band
In short: Before they were heavy metal pioneers, Deep Purple were a revolving door of musicians known as Roundabout. From orchestral collaborations to a 1972 concert officially recognized as the loudest on Earth, discover how a shifting lineup transformed a studio project into a global phenomenon.
Deep Purple’s origins were far from heavy metal. Formed in London in 1968, the group—initially called Roundabout—began as a psychedelic and progressive rock outfit. The project was driven by the vision of Chris Curtis, who imagined a 'supergroup' where members could rotate like a musical roundabout. However, after the original lineup featured Rod Evans and Nick Simper, the band underwent a radical transformation in 1969.
The shift to a heavier, more aggressive sound was cemented by the 'Mark II' lineup, which brought in Ian Gillan and Roger Glover. This era produced the seminal 1970 album 'Deep Purple in Rock', a record that helped codify the heavy metal genre alongside contemporaries like Led Zeppelin and Black Sabbath. The band's reputation for sheer power was solidified in 1972, when the Guinness Book of World Records listed them as 'the globe's loudest band' following a performance at London's Rainbow Theatre.
The band's musical identity was a constant tug-of-war between classical influences and hard rock. Keyboardist Jon Lord pushed for orchestral grandeur, notably through the 1969 'Concerto for Group and Orchestra' at the Royal Albert Hall. While guitarist Ritchie Blackmore initially sought to move away from these classical textures toward a harder rock style, the interplay between Lord's distorted organ and Blackmore's guitar became the band's signature. Despite frequent lineup changes and the eventual departure of key members like Blackmore in 1975, the band's legacy remains immense, with over 100 million records sold worldwide.
