Charli xcx's Darker Vibes Hit ACL Festival Stage

Charli xcx headlined the American Express stage at Austin City Limits Music Festival on Friday, October 2, 2026. Her set felt sleek, with a darker vibe from her new music.

The crowd still loved her, despite not totally getting the new vibe. During her collaboration with Billie Eilish on 'Guess', underwear exploded from the stage in a cloud of confetti, leaving one reporter wondering who would clean up the muddy panties.

Troye Sivan made a surprise appearance on stage during Charli xcx's set.
