Olivia Rodrigo is drawing inspiration from one of music's most influential female-led festivals as she launches her own event aimed at supporting women and girls.Speaking with ABC News' Diane Sawyer in an interview that aired Tuesday on "Good Morning America," the Grammy-winning singer said Lilith Fair, the groundbreaking concert tour founded by Sarah McLachlan in the 1990s, helped inspire Daisy Chain Fields, a new music festival taking place Aug. 29 at Great Park in Irvine, California."Lilith Fair was a huge inspiration in me starting this festival, Daisy Chain Fields," Rodrigo said. "And actually, the first person that I called when I decided that I wanted to do this festival was Sarah McLachlan."Rodrigo added that McLachlan "is a total trailblazer and an incredible artist and a friend, and she's actually going to sing at the festival with me too, which is really exciting and a big honor for me."Sarah McLachlan attends the premiere of "Lilith Fair: Building A Mystery" during the 2025 Toronto International Film Festival on September 13, 2025 in Toronto, Ontario.Mathew Tsang/Getty ImagesThe single-day festival will bring together an all-women lineup of artists, including Rodrigo, Chappell Roan, Doechii, Bikini Kill, Garbage, Mitski, KATSEYE, The Breeders and more. Special guests will include McLachlan, Stevie Nicks and Karen O."I'm so excited about the lineup," Rodrigo said. "My friend Chappell Roan is going to do it, Doechii, Bikini Kill ... Kathleen Hanna is a huge hero of mine."According to organizers, 100% of the net proceeds from Daisy Chain Fields will benefit nonprofit organizations dedicated to advancing and advocating for women and girls.Rodrigo said the festival's mission extends beyond music.Popular Reads"All of the incredible artists who are on the bill are doing it for free for charity, which is just a real testament to their hearts, as well as their talent," she said.The singer said she came up with the festival's name while imagining a community-centered gathering.Ahead of the launch of Daisy Chain Fields, Olivia Rodrigo sat down with ABC News' Diane Sawyer for an exclusive interview airing on "Good Morning America."ABC News"When I pictured this festival, I had an image in my head of girls sitting underneath a tree, making [daisy chain] flower crowns or friendship bracelets," Rodrigo said. "And so I came up with the name Daisy Chain Fields, and I also just like the idea of a daisy chain, how we can all be individual links in this chain that is larger than the individual."Beyond the performances, the festival will feature nonprofit activations, educational resources, community art experiences, local vendors and immersive installations. Participating organizations include Baby2Baby, Planned Parenthood, the National Women's Law Center, the Center for Reproductive Rights, the National Domestic Workers Alliance and more.Rodrigo said Daisy Chain Fields is ultimately about fostering connection and support among women."I think there's this rhetoric that girls are supposed to be competing with each other for the top spot, or there's only this many resources for everyone," Rodrigo said. "And I think it's an experience like Lilith Fair, and hopefully Daisy Chain, that will show us that we're all way stronger when we come together and support one another."Monday's festival announcement comes as Rodrigo celebrates the release of her third studio album, "You Seem Pretty Sad for a Girl So in Love." The album debuted June 12, selling 485,000 units in its first week, according to a festival press release, while its lead single, "Drop Dead," made Rodrigo the first artist to debut the lead singles off their first three albums at No. 1.
