Olivia Rodrigo turned a Balenciaga moment into the night’s sharpest surprise at Lollapalooza, stepping onto the stage with Smashing Pumpkins to sing “Thirty-Three.” Billy Corgan had already pulled Yungblud into the set, turning a standard festival slot into a rolling guest appearance sequence.
Yungblud joins in under an hour
Less than an hour after his own set, Yungblud returned for “Luna,” and Corgan played guitar beside him. Yungblud’s onstage line — “This is a fucking dream come true!” — made the handoff explicit: this was not a routine cameo, but a live crossover built in real time.
1993 matters here because that is when Smashing Pumpkins released Siamese Dream, which included “Luna.” The song choice pulled the crowd back to the band’s Seventies-leaning archive without pretending the guests belonged to that original era; that contrast is the point, and it is why the sequence felt planned for impact rather than nostalgia by accident.
Rodrigo in sheer baby doll
Olivia Rodrigo came out soon after in a sheer baby doll dress and knee high stockings, with Corgan switching to acoustic for “Thirty-Three.” Billy Corgan introduced her with, “And now I’d like to bring out a very, very special guest. Miss Olivia Rodrigo!” and the set moved from electric guest spot to stripped-down feature in one song.
1995 is the other anchor in the setlist logic: that is when Smashing Pumpkins released Mellon Collie and the Infinite Sadness, which included “Thirty-Three.” Rodrigo was framed as a special guest from outside the band’s original era, yet she was inserted into one of the group’s most recognizable songs, making the appearance feel less like novelty and more like a deliberate bridge between generations.
Chicago gets the week’s repeat pattern
Earlier in the week, Smashing Pumpkins had already used the Lollapalooza aftershow for another guest-heavy run, bringing out Barry Williams for “It’s a Sunshine Day” and Melissa Auf der Maur for “The Everlasting Gaze.” That earlier sequence set up a pattern: the band is not just revisiting its catalog, it is using guest spots to redraw it in front of a Chicago audience.
2000 also fits into that pattern, because Melissa Auf der Maur sang “The Everlasting Gaze” with the band then as a touring member. The aftershow and the main set together make the week feel curated around callbacks, but Rodrigo’s appearance carried the widest crossover effect because it paired a current pop star with a legacy rock act in the same rain-soaked, red-lit frame.
The best read on the night is simple: Billy Corgan used Lollapalooza to turn old material into live event programming, and Olivia Rodrigo was the sharpest booking of the run. If the question is why she and Yungblud fit the slot, the answer is in the set itself — both guests expanded the band’s reach without changing the songs that made the moment work.
