Friday, July 31, was the night Rodrigo appeared, according to multiple post-festival reports. The official Lollapalooza schedule shows the festival’s four days as July 30, July 31, Aug. 1 and Aug. 2, and web recaps described Rodrigo’s appearance as a surprise rather than a billed set. Lollapalooza’s main festival page says the event took place in Chicago’s Grant Park and featured more than 170 artists across eight stages.

(iheart.com) TikTok posts tied to audience-shot video said Rodrigo and The Smashing Pumpkins performed “33,” while an Aug. 1 recap spelled the title out as the band’s 1995 song “Thirty-Three.” MSN’s festival recap said Rodrigo joined the band for a duet that helped turn the moment into one of the weekend’s most-circulated clips. (inmusicblog.com) Girls’ Life separately grouped the appearance with other high-profile pop moments from the festival weekend. ### Why did the appearance get so much attention? Chicago was central to the setup. iHeart said The Smashing Pumpkins were playing their first Lollapalooza headlining slot in 32 years, dating back to 1994, and USA Today described the performance as the band’s first Lollapalooza appearance since that year.
