The inaugural Daisy Chain Fields music festival is scheduled to take place Saturday at Great Park in Irvine. Olivia Rodrigo will headline the event, leading an all-women lineup that includes performers such as Chappell Roan, Doechii, Garbage, Mitski, and The Breeders. Organizers have designed the festival to feature two performance areas with no overlapping sets, allowing attendees to see every scheduled act. The festival is expected to accommodate up to 45,000 people, utilizing the city-owned Great Park Live amphitheater and additional park space for a main stage.

Additional artists performing include Bikini Kill, Die Spitz, Eli, KATSEYE, Not For Radio, Quiet Light, Rachel Chinouriri, and Santigold. Olivia Rodrigo is scheduled to close the festival from 8:40 p.m. to 10 p.m. on the Dandelion Stage. Special guests for the event include Karen O, Sarah McLachlan, and Stevie Nicks.

Rodrigo stated in June that the festival was created around an all-women lineup, with 100% of net proceeds benefiting charities dedicated to advancing and advocating for women and girls. She expressed her hope that "joy, community, and music can be the drivers of meaningful change" through the festival. This effort aligns with her Fund 4 Good initiative, launched in 2024 to support reproductive rights, education, and efforts addressing domestic violence. Beneficiaries include Baby2Baby, Black Mamas Matter Alliance, Center for Reproductive Rights, FreeFrom, Jhpiego, Johns Hopkins Center for Indigenous Health, National Domestic Workers Alliance, National Institute for Reproductive Health, National Women's Law Center, and Planned Parenthood.

The festival will occur amid concerns about high temperatures in Irvine. The National Weather Service forecasts temperatures of about 93 degrees on Saturday, with the hottest period anticipated between 10 a.m. and 4 p.m., when many performances will be underway. To address these conditions, a festival map indicates five hydration stations, five cooling stations, two shaded areas, and two medical tents will be available to attendees.

Irvine Councilman William Go, who chairs the Great Park Board, commented on the festival's announcement, calling it a "milestone moment for Irvine and for our vision of creating a world-class cultural destination." The event represents a significant use of Great Park facilities for a large-scale public gathering.
