Olivia Rodrigo brought her GUTS world tour to a meaningful close at Lollapalooza in Chicago on August 1 by surprising fans with a performance alongside Weezer during her headline set. The rock veterans joined her onstage to play classics “Buddy Holly” and “Say It Ain’t So,” bringing full-circle magic—Weezer was her first-ever live concert experience. Rodney, still emotional about the moment, told the crowd, “I’m so over the moon because that incredible band is actually here tonight.” With this performance, Olivia punctuated her era and looked ahead to new chapters in her musical journey.
