Taking over the fields of Grant Park for four days each summer, Lollapalooza is a behemoth of a music festival, welcoming an estimated 100,000 attendees to a sea of stages, brand activations and concession stands set beneath the beating sun. This year, pop princess Ariana Grande, rapper Childish Gambino, alt-rock duo Twenty One Pilots, rockers the Strokes, psych act Tame Impala and EDM hit-makers the Chainsmokers headline the main stages. Some people come for the music, some come for the people-watching and others come to get drunk on a blanket in the middle of a field—there's no wrong way to Lolla.
Four-day passes to Lollapalooza are currently on sale, including general admission and VIP varieties. One-day tickets to the festival will go on sale in the coming weeks when the festival's single-day lineups are released.
