Oasis was a British rock band formed in Manchester in 1991. Notably featuring brothers Liam and Noel Gallagher, the band's style was characterized by a fusion of Beatles-influenced pop melodies with the grit and aggression of punk and rock, exemplified in hits like "Wonderwall" and "Don't Look Back in Anger". During the 1990s, Oasis was a significant part of the Britpop movement, often in rivalry with fellow Britpop band Blur. Their album, "(What's the Story) Morning Glory?" is considered one of the most significant albums in British music history due to its commercial success and cultural impact.
