Arctic Monkeys are an English indie rock band formed in 2002 in High Green, a suburb of Sheffield. The band consists of Alex Turner (lead vocals, rhythm guitar), Jamie Cook (lead guitar, backing vocals in the early days), Nick O'Malley (bass, backing vocals), and Matt Helders (drums, backing vocals). Former band member Andy Nicholson (bass guitar, backing vocals) left the band in 2006 shortly after its debut album was released.They have released five studio albums: Whatever People Say I Am, That's What I'm Not (2006), Favourite Worst Nightmare (2007), Humbug (2009), Suck It and See (2011) and AM (2013), as well as one live album, At the Apollo (2008). Their debut album is the fastest-selling debut album by a band in British chart history, and in 2013, Rolling Stone ranked it the 30th greatest debut album of all time.The band have won seven Brit Awards—winning both Best British Group and Best British Album three times, and have been nominated for three Grammy Awards. They also won the Mercury Prize in 2006 for their debut album, in addition to receiving nominations in 2007 and 2013. The band have headlined at the Glastonbury Festival twice, in 2007 and again in 2013.Arctic Monkeys were heralded as one of the first bands to come to public attention via the Internet (through 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.
