Lollapalooza is returning to Grant Park, Chicago this year and featuring the likes of Tyler, the Creator; Megan Thee Stallion and more. The music festival unveiled its official lineup on Wednesday afternoon (May 19) ahead of its summer dates.

“Your 2021 Lineup. Tickets On-Sale today at 12pm CT,” the festival captioned its Twitter and Instagram posts.

The festival’s full lineup will feature a total of 165 acts, including Tyler, the Creator; Megan Thee Stallion, Young Thug, Post Malone, DaBaby, Roddy Ricch, Brockhampton, Jack Harlow, Trippie Redd, Playboi Carti, Kaytranada, Polo G, Marshmello, Flo Milli, iann dior, Rico Nasty, JPEGMAFIA, Toosii and many more.

Lollapalooza, and many other fests, were canceled last year in a nationwide sweep due to the COVID-19 pandemic. However, several festivals are set to return later this year, including New York City’s Governors Ball and Travis Scott’s Astrowrold, as more and more Americans get vaccinated against the deadly disease.

According to Lollapalooza’s official website, guests will be required to get fully vaccinated against COVID-19 or test negative for the virus before they can enter festival grounds.

“In accordance with current local public health guidance, full COVID-19 vaccination or negative COVID-19 test results will be required to attend Lollapalooza 2021,” the site reads.

“For patrons who are not fully vaccinated, a negative COVID-19 test result must be obtained within 24 hours of attending Lollapalooza each day. Details on the festival entry process will be available in early July,” it added.

To encourage people to get vaccinated, the City of Chicago will also partner with Lollapalooza in the days leading up to the festival.

Tickets for Lollapalooza 2021 go on sale today at 10 a.m. PST/ 12 p.m. CT / 1 p.m. EST. The fest returns this year to Grant Park from July 29 to Aug. 1. See the full lineup below.
