Problem: Background: The Roots is an American hip hop band, formed in 1987 by Tariq "Black Thought" Trotter and Ahmir "Questlove" Thompson in Philadelphia, Pennsylvania, United States. The Roots are known for a jazzy and eclectic approach to hip-hop featuring live musical instruments. Malik B., Leonard "Hub" Hubbard, and Josh Abrams were added to the band (formerly named "The Square Roots"). Since its first independent album-length release the band has released 10 studio albums, two EPs, two collaboration albums (with other artists), and also collaborated on recordings and in live shows with a wide variety of artists in many musical genres.
Context: The Roots originated in Philadelphia with Ahmir "Questlove" Thompson and Tariq "Black Thought" Trotter while they were both attending the Philadelphia High School for the Creative and Performing Arts. They would busk out on the street corners with Questlove playing bucket drums and Tariq rapping over his rhythms. Their first organized gig was a talent show in 1989 at the school where they used the name Radio Activity, which began a series of name changes that progressed through Black to the Future and then The Square Roots. In 1992, they dropped the "Square" because a local folk group had claim to the name.  Organix was the band's first album, released and sold independently in 1993. It drew offers from music labels, and the band signed with DGC/Geffen. The Roots' first album for DGC, Do You Want More?!!!??!, was released in 1994. It was a moderate hit among alternative music fans, boosted by the group's appearance at Lollapalooza. The band performed at the Montreux Jazz Festival that year. Touring guests, beatboxer Rahzel and producer Scott Storch, joined The Roots.  The 1996 release Illadelph Halflife was the group's first album to break the Top 40 on the Billboard 200 chart, spurred in part by MTV's airplay of the video for "What They Do" (a parody of rap video cliches) and "Clones", which was their first single to reach the top five on the rap charts. "What They Do" was also the group's first single to hit the Top 40 of Billboard's charts, reaching a peak of #34. While continuing on the path of live instrumentation, the album's sound was somewhat darker.
Question: Who started it
Answer: Ahmir "Questlove" Thompson and Tariq "Black Thought" Trotter

Background: 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".
Context: 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.

Blackmore suggested a new name: "Deep Purple", named after his grandmother's favourite song.
