Oasis was an English rock band formed in Manchester in 1991. Originally known as the Rain, the group initially consisted of Liam Gallagher (lead vocals, tambourine), Paul Arthurs (guitar), Paul McGuigan (bass guitar) and Tony McCarroll (drums). Liam's older brother Noel (lead guitar, vocals) later joined as a fifth member, finalising the group's core lineup. During the course of their existence, they had various lineup changes, with the Gallagher brothers remaining the only staple members.
