Tickets for the 2021 Austin City Limits Music Festival will go on sale May 20 at noon following a reveal of the festival's lineup at 10 a.m., according to an announcement by ACL.

ACL will take place at Zilker Park across two weekends this year, Oct. 1-3 and 8-10. Presale of three-day passes to American Express cardholders is already underway, with prices beginning at $275. Several tiers of tickets are available: general admission; general admission plus, which offers access to a private lounge and restrooms; VIP; and Platinum.

Specifics on health and safety protocols, including capacity restrictions, have not yet been announced.

"The safety of fans, artists and staff remains our top priority. ACL Fest organizers are in regular communication with local health and public safety officials and will follow current recommendations and guidelines in place at the time of the festival," festival communications said. "As the weekends approach, ACL Fest patrons will receive regular updates with important information regarding safety policies and procedures before entering Zilker Park."

Lollapalooza, another large music festival held in Chicago in late summer, released details about its lineup and COVID-19 safety protocols May 19. It will require evidence of vaccination or a negative coronavirus test before entry.

ACL has not announced a similar protocol, but said it would partner with Austin Public Health officials to "encourage vaccination in the months prior to the festival."
