Olivia Rodrigo delivered alongside surprising guests Weezer as Lollapalooza continued in Chicago with performances by T-Pain, Flipturn, Gigi Perez, Bo Staloch and more.

Olivia Rodrigo delivered a powerful performance Friday night as she made her Lollapalooza Chicago debut, headlining Day Two of the annual music festival in Grant Park. Rodrigo, currently on her GUTS World Tour, performed a mix of fan favorites from her Grammy-winning debut album SOUR and her chart-topping follow-up GUTS.

She’s powerful, she’s political, she’s rock and she’s pop. And she brought out surprise guest Weezer for two songs during her Friday headlining concert in Grant Park.
