Here are five things to know about Saturday at the Austin City Limits Music Festival and what's coming up Sunday:

1. Saturday night’s headliners were 1980s rock legends the Cure and hip-hop artist Childish Gambino, aka Donald Glover. Glover, also an actor, has said that he plans to retire his musical alter ego when his tour ends Saturday. Standout acts early in the day included hip-hop up-and-comer Alabama Shakes frontwoman Brittany Howard, who shook the stage with a powerful set; Taylor Bennett, the younger brother of 2017 ACL Fest headliner Chance the Rapper; and Norwegian pop singer Sigrid, who made an impressive showing in the blazing heat.

2. Sigrid actually spoke for all the festivalgoers standing in the unforgiving sun: “It’s warm. You must be used to this heat,” she said to the Austin audience. (Later in the set, she sat down on her piano stool and immediately jolted with a quick “Oooh! It’s so warm!”) Temperatures hit the mid-90s, with high humidity. Lines were long at hydration stations; we spied festival staff handing out water in the crowd, and the fest reminded people to hydrate and stay safe through app alerts.

3. Goop, anyone? In the early afternoon, while crowds were still arriving, a small crowd gathered in a shady patch of grass near the wine grove for a session hosted by Gwyneth Paltrow’s high-end wellness brand. In a fest first, people who stopped by the meditation exercise session were invited to welcome “clean energy” into their bodies with breathwork and easy movement at the Bonus Tracks stage.

4. Billie Eilish has arrived. The teen pop singer made a stop at the Bonus Tracks stage, too, to talk to NPR. It was hard to hear the conversation over the shrieks of adoring fans. Among the details revealed: Eilish “thought everyone would hate” her enormous hit song “Bad Guy” when she recorded it. “I want to make what I want to make and expect nothing,” she said. She took to the Honda stage at 6 p.m., opposite hometown hero Gary Clark Jr. across the park.

5. Weekend One of the festival comes to a close Sunday, with headliners Cardi B and Mumford & Sons. Also expected to draw crowds: chart-topping rapper Lizzo and country singer Kacey Musgraves, who is a Willie Nelson pal and former Austinite. And then it all starts over for Weekend Two on Friday.
