Oasis are an English rock band formed in Manchester in 1991. The group initially consisted of Liam Gallagher (lead vocals), Paul "Bonehead" Arthurs(guitar), Paul "Guigsy" McGuigan (bass guitar) and Tony McCarroll (drums). Liam asked his older brother Noel Gallagher (lead guitar, vocals) to join as a fifth member a few months later to finalise their formation. Noel became the de factoleader of the group and took over the songwriting duties for the band's first four albums. They are regarded as the most globally successful group of the Britpop era and one of the most influential rock bands of all time
