Arctic Monkeys are an English alternative rock band from High Green, a suburb of Sheffield, England. Formed in 2002, the band currently consists of Alex Turner (lead vocals, guitar), Jamie Cook (guitar), Nick O'Malley (bass guitar, backing vocals), Matt Helders (drums, backing vocals) and John Ashton as a touring member (keyboard, guitar, backing vocals). Former members include Andy Nicholson (bass guitar, backing vocals) and Glyn Jones (lead vocals, guitar). Their debut album "Whatever People Say I Am, That's What I'm Not", released in early 2006, became the fastest-selling debut album in British music history, surpassing "Oasis's Definitely Maybe" and remains the fastest-selling debut album for a band in the United Kingdom. Since then the band have released two more albums: "Favourite Worst Nightmare" (2007) and "Humbug" (2009). Arctic Monkeys are heralded as one of the first acts to come to the public attention via the Internet (fan-based sites rather than from the band), with commentators suggesting they represented the possibility of a change in the way in which new bands are promoted and marketed.
