Arctic Monkeys are an English rock band formed in 2002 in High Green, a suburb of Sheffield. The band consists of Alex Turner (lead vocals, guitar, piano), Matt Helders (drums, vocals), Jamie Cook (guitar) and Nick O'Malley (bass guitar, backing vocals). Former band member Andy Nicholson (bass guitar, backing vocals) left the band in 2006 shortly after their debut album was released. They have released six 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), AM (2013), and Tranquility Base Hotel & Casino (2018), as well as one live album, At the Apollo (2008). Their debut album is the fastest-selling debut album by a band in UK chart history, and in 2013, Rolling Stone ranked it the 30th-greatest debut album.
