Lollapalooza, the major music festival that dominates Chicago Il’s Grant Park, is back for its 30th anniversary July 29- Aug. 1.

In their grand return after a year-long hiatus due to COVID-19, they boast headliners Tyler, The Creator, Miley Cyrus, Post Malone and Foo Fighters. The four-day festival will also include heavy hitters such as Megan Thee Stallion, Journey, Kaytranada, Orville Peck, Flo Milli, White Reaper, Porches and more. In total, there is nearly 170 different acts on the festival bill over the four days.

While the festival will be operating at full capacity (it has reached up to 400,000 in the past), all attendees must be fully vaccinated. So, bring along those cards you held up for your “vaxx selfie.” If not vaccinated, attendees must provide a negative COVID-19 test obtained within 24 hours of each festival day. The festival team encourages concert-goers to find their nearest vaccination site at vaccinefinder.org. Further details on the festival entry process will be available in early July, however specific questions or concerns can be directed to info@lollapalooza.com. Four-day tickets are now on sale but single-day tickets are not yet available.

The festival also features performances from Mt. Joy, Band of Horses, Jimmy Eat World, The Front Bottoms, Steve Aoki, Modest Mouse, All Time Low, Marc Rebillet and Young Thug. See below for full lineup:
