The idea to create Gorillaz came about when the two were watching MTV: "If you watch MTV for too long, it's a bit like hell—there's nothing of substance there. So we got this idea for a cartoon band, something that would be a comment on that," Hewlett said. The band's music is a collaboration between various musicians, Albarn being the only permanent musical contributor, and incorporates influences including alternative rock, Britpop, dub, hip-hop, and pop music. In 2001, the band's eponymous debut album sold over seven million copies, and featured hits such as the songs "19-2000" and "Clint Eastwood," earning them an entry in the "Guinness Book of World Records" as the Most Successful Virtual Band.
