Problem: Deep Purple are an English rock band formed in Hertford in 1968. The band is considered to be among the pioneers of heavy metal and modern hard rock, although their musical approach changed over the years. Originally formed as a progressive rock band, the band shifted to a heavier sound in 1970. Deep Purple, together with Led Zeppelin and Black Sabbath, have been referred to as the "unholy trinity of British hard rock and heavy metal in the early to mid-seventies".

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. Curtis' vision was a "supergroup" where the band members would get on and off, like a musical roundabout. Impressed with the plan, Edwards agreed to finance the venture with his two business partners John Coletta and Ron Hire, who comprised Hire-Edwards-Coletta Enterprises (HEC). The first recruit to the band was the classically trained Hammond organ player Jon Lord, Curtis' flatmate who had most notably played with the Artwoods (led by Art Wood, brother of future Rolling Stones guitarist Ronnie Wood, and including Keef Hartley). Lord was then performing in a backing band for the vocal group The Flower Pot Men (formerly known as the Ivy League), along with bassist Nick Simper and drummer Carlo Little. Simper had previously been in Johnny Kidd and the Pirates and survived the 1966 car crash that killed Kidd. Lord put the two on alert that he'd been recruited for the Roundabout project, after which Simper and Little suggested guitarist Ritchie Blackmore, whom Lord had never met. Simper had known Blackmore since the early 1960s when his first band, the Renegades, debuted around the same time as one of Blackmore's early bands, the Dominators. HEC persuaded Blackmore to return from Hamburg to audition for the new group. Blackmore was making a name for himself as a studio session guitarist, and had also been a member of the Outlaws, Screaming Lord Sutch, and Neil Christian. Curtis' erratic behaviour and lifestyle, fuelled by LSD use, caused a sudden disinterest in the project he had started, forcing HEC to dismiss him from Roundabout. But HEC was now intrigued with the possibilities Lord and Blackmore brought, while Lord and Blackmore were also keen to continue. The two carried on, recruiting additional members and keeping Tony Edwards as their manager. Lord convinced Simper to join for good, but left Carlo Little behind in favour of drummer Bobby Woodman. In March 1968, Lord, Blackmore, Simper and Woodman moved into Deeves Hall, a country house in South Mimms, Hertfordshire. The band would live, write and rehearse at Deeves Hall, which was fully kitted out with the latest Marshall amplification. According to Simper, "dozens" of singers were auditioned (including Rod Stewart and Woodman's friend Dave Curtiss)until the group heard Rod Evans of the club band The Maze, and thought his voice fit their style well. Tagging along with Evans was his band's drummer, Ian Paice. Blackmore had seen Paice on tour with The Maze in Germany in 1966, and had been impressed by the 18-year-old's drumming. The band hastily arranged an audition for Paice, given that Woodman was vocally unhappy with the direction of the band's music. Both Paice and Evans won their respective jobs, and the line-up was complete. During a brief tour of Denmark and Sweden in April, in which they were still billed as Roundabout, Blackmore suggested a new name: "Deep Purple", named after his grandmother's favourite song. The group had resolved to choose a name after everyone had posted one on a board in rehearsal. Second to Deep Purple was "Concrete God", which the band thought was too harsh to take on.

How did they come up with the name Roundabout?

Problem: Black Sabbath were an English rock band, formed in Birmingham in 1968, by guitarist and main songwriter Tony Iommi, bassist and main lyricist Geezer Butler, singer Ozzy Osbourne, and drummer Bill Ward. Black Sabbath are often cited as pioneers of heavy metal music. The band helped define the genre with releases such as Black Sabbath (1970), Paranoid (1970) and Master of Reality (1971). The band had multiple line-up changes, with Iommi being the only constant member throughout its history.

The remaining two original members, Tony Iommi and Geezer Butler, began auditioning new singers for the band's next release. Samson's Nicky Moore, and Lone Star's John Sloman were considered and Iommi states in his autobiography that Michael Bolton auditioned for the band. The band settled on former Deep Purple vocalist Ian Gillan to replace Ronnie James Dio in December 1982. While the project was not initially set to be called Black Sabbath, pressures from the record label forced the group to retain the name. The band entered The Manor Studios in Shipton-on-Cherwell, Oxfordshire, in June 1983 with a returned and newly sober Bill Ward on drums. Born Again (7 August 1983) was panned upon release by critics. Despite the negative reception of the album, it reached number four on the UK charts, and number 39 in the U.S. Even a decade after its release AllMusic's Eduardo Rivadavia called the album "dreadful", noting that "Gillan's bluesy style and humorous lyrics were completely incompatible with the lords of doom and gloom". Although he performed on the album, drummer Ward was unable to tour because of the pressures of the road, and quit the band after the commencement of the Born Again album. "I fell apart with the idea of touring", Ward later said. "I got so much fear behind touring, I didn't talk about the fear, I drank behind the fear instead and that was a big mistake." Ward was replaced by former Electric Light Orchestra drummer Bev Bevan for the Born Again '83 -'84 world tour, (often unofficially referred to as the 'Feigh Death Sabbath '83 - '84' World Tour) which began in Europe with Diamond Head, and later in the U.S. with Quiet Riot and Night Ranger. The band headlined the 1983 Reading Festival in England, adding the Deep Purple song "Smoke on the Water" to their set list. The tour in support of Born Again included a giant set of the Stonehenge monument. In a move that would be later parodied in the mockumentary This Is Spinal Tap, the band made a mistake in ordering the set piece. As Geezer Butler later explained: We had Sharon Osbourne's dad, Don Arden, managing us. He came up with the idea of having the stage set be Stonehenge. He wrote the dimensions down and gave it to our tour manager. He wrote it down in metres but he meant to write it down in feet. The people who made it saw fifteen metres instead of fifteen feet. It was 45 feet high and it wouldn't fit on any stage anywhere so we just had to leave it in the storage area. It cost a fortune to make but there was not a building on earth that you could fit it into.
