Oasis were an English rock band formed in Manchester in 1991. Developed from an earlier group, the Rain,
the band originally consisted of Liam Gallagher (lead vocals, tambourine), Paul Arthurs (guitar), Paul McGuigan (bass guitar),
and Tony McCarroll (drums).Upon returning to Manchester, Liam's older brother, Noel Gallagher (lead guitar, vocals) joined as a fifth member, which formed the band's core and settled line-up.
During the course of their existence, they had various line-up changes, though the Gallagher brothers remained as the staple members until the group's dissolution.

Oasis signed to independent record label Creation Records in 1993 and released their record-setting debut album Definitely Maybe (1994). The following year the band recorded
(What's the Story) Morning Glory? (1995) with drummer Alan White, in the midst of a chart rivalry with Britpop peers Blur.(What's the Story) Morning Glory? became one of the best-selling albums of all time,
and the Gallagher brothers were featured regularly in tabloid newspapersfor their sibling disputes and wild lifestyles.Oasis' third album, Be Here Now (1997),
went on to be the fastest-selling album of all time in Britain at the time upon release.
