Charli XCX delivered an energetic mainstage set at Coachella 2025, drawing heavily from her 'Brat' album and reigniting the cultural phenomenon of 'Brat Summer.' The performance included surprise appearances by Troye Sivan, Lorde, and Billie Eilish, who joined her for collaborative tracks, thrilling the audience. Following her set, Charli sparked debate by wearing a 'Miss Should Be Headliner' sash at an afterparty, seen as a critique of Green Day's headlining status. Green Day's politically charged performance featured altered lyrics addressing MAGA supporters and the struggles of Palestinian children, adding a socio-political dimension to the festival. Bernie Sanders made a surprise appearance, introducing Clairo's set and urging younger generations to confront systemic challenges and advocate for change.
