Deep Purple are an English rock band formed in Hertford in 1968. Along with Led Zeppelin and Black Sabbath, they are considered to be among the pioneers of heavy metal and modern hard rock, although some band members believe that their music cannot be categorised as belonging to any one genre. They were once listed by the Guinness Book of World Records as ”the loudest pop group”, and have sold over 100 million albums worldwide. Deep Purple were ranked #22 on VH1′s Greatest Artists of Hard Rock programme.
The band has gone through many line-up changes and an eight-year hiatus (1976–84). The 1968–76 line-ups are commonly labelled Mark I, II, III and IV. Their second and most commercially successful line-up featured Ian Gillan (vocals), Jon Lord (keyboards),Roger Glover (bass), Ian Paice (drums) and Ritchie Blackmore (guitar).
