Sombr, a 21-year-old musician from New York, entered Lollapalooza with a classic muscle car and a margarita in hand. The only other notable performer was Billy Corgan, the frontman of the Smashing Pumpkins. Other special guests included 5 Seconds Of Summer, who Sombr praised as "the greatest band in the f***ing world." Despite some questioning his overnight rockstar status, Sombr remains committed to his music. He has been open about his struggles with self-image, making him more relatable to his young fanbase. His new song "My Body Isn't Ready" is about his issues with body image, a struggle he has had his whole life.
