Olivia Rodrigo's passion project comes to life today: Daisy Chain Fields, the sold-out charity music festival she founded, kicks off Saturday at Great Park in Irvine, California, with 100% of net proceeds benefiting charities that support women and girls, according to Great Park Live.

The all-women lineup spans generations and genres: Rodrigo headlines alongside Chappell Roan, Doechii, Garbage, KATSEYE, Mitski, Santigold, The Breeders and Bikini Kill across two stages, with special guest appearances expected from Stevie Nicks, Sarah McLachlan and Karen O, per Rolling Stone.

Tickets for the inaugural festival sold out in just 30 minutes when they went on sale earlier this year, with every remaining option landing on a waitlist. The festival arrives days after Rodrigo released the politically charged charity single "Serena Joy," with proceeds also funneling toward the festival's fundraising goals.

Organizers and Irvine city officials are bracing for heavy weekend crowds and peak-summer heat at the Great Park venue.
