Gorillaz are a British virtual band created in 1998 by Damon Albarn of rock band Blur, and Jamie Hewlett, co-creator of the comic bookTank Girl. While watching MTV, Hewlett came up with the idea to create the band, and later commented, "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." Gorillaz is a virtual band consisting of four cartoon characters: 2D, Murdoc, Noodle and Russel. They are used in promotional material such as album covers, posters, and in concerts, during which holographic versions of the characters are used. The band's music is a collaboration between various musicians; Albarn is the only permanent musical contributor. Gorillaz have released four studio albums, all on the Parlophone and Virgin record labels: Gorillaz (2001), Demon Days (2005),, Plastic Beach (2010) and The Fall (digital in 2010, physical in 2011).
