Chappell Roan, a 26-year-old pop sensation, achieved a historic milestone at Lollapalooza by drawing what is believed to be the largest daytime crowd in the festival's history. Initially scheduled to perform on a smaller stage, Roan was moved to the main stage due to overwhelming fan interest, a decision vindicated by her massive audience. Known for her eclectic style and queer-themed lyrics, Roan's performance included hits like 'Good Luck, Babe!' and 'Hot To Go!'. Organizers and attendees described the performance as a magical addition to Lolla's legacy, with estimates suggesting it may be the biggest set ever at the festival. Roan's rise to fame has been marked by significant appearances at other major festivals and her debut album, 'The Rise and Fall of a Midwest Princess', which has gained a cult following.
