Deep Purple are an English rock band formed in Hertfordshire 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 have tried not to label themselves any one genre. The band have also incorporated pop and progressive rock elements Deep Purple Bio by Jason Ankeny & Greg Prato of All Music Guide. They were once listed by the Guinness Book of World Records as the world's loudest band,[http://uk.real.com/music/artist/Deep_Purple/ Deep Purple - Hard Rock - Rock/Pop - Music - www.real.com ] and it has sold over 100 million albums worldwide. Deep Purple was ranked #22 on VH1's Greatest Artists of Hard Rock program.

The band has gone through many line-up changes and an eight-year hiatus. 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), Ritchie Blackmore (guitar), Jon Lord (keyboards), Roger Glover (bass guitar) and Ian Paice (drums). This line-up was active 1969-73 and was revived from 1984-89 and again in 1993 before the rift between Blackmore and other members became unbridgeable. The current line-up including guitarist Steve Morse has been much more stable, though Lord's retirement in 2002 has left Paice as the only original member.

(1967–1968) Pre-Deep Purple years

In 1967, former Searchers drummer Chris Curtis contacted London businessman Tony Edwards in the hope that he would manage a new group he was putting together, to be called Roundabout: so-called because the members would get on and off the band, like a musical roundabout. Impressed with the plan, Edwards agreed to finance the venture with two business partners: John Coletta and Ron Hire (Hire-Edwards-Coletta - HEC Enterprises).

The first recruit was the classically-trained Hammond organ player Jon Lord, who had most notably played with The Artwoods (led by Art Wood, brother of future Rolling Stones guitarist Ronnie Wood, and featuring Keef Hartley). He was followed by session guitarist Ritchie Blackmore, who was persuaded to return from Hamburg to audition for the new group. Curtis soon dropped out, but HEC Enterprises, as well as Lord and Blackmore, were keen to carry on.

For the bass guitar, Lord suggested his old friend Nick Simper, with whom he had played in a band called The Flower Pot Men and their Garden (formerly known as The Ivy League) back in 1967. Simper's claims to fame (apart from Purple) were that he had been in Johnny Kidd & The Pirates and had been in the car crash that killed Kidd. He was also in Screaming Lord Sutch's The Savages, where he played with Blackmore.
