Liam Gallagher and Noel Gallagher are the brothers at the centre of Oasis, the Manchester band whose songs and sibling rivalry became a defining part of 1990s British music culture. Short clips featuring the pair circulate online because fans instantly recognise their voices, attitudes and contrasting styles, even without context. On soundboards and in short videos, a four-second Liam and Noel moment works as shorthand for Oasis itself, for Britpop nostalgia and for the kind of brotherly tension that made the band as famous off stage as on it.
