SAN FRANCISCO — As much as Billie Eilish is a pop sensation, she’s also a conductor of chaos in concert. The thousands in attendance at Eilish’s sold-out show at Chase Center on Tuesday hung on the singer’s every word. When Eilish sang, they sang, and when she jumped, they jumped. The connection between artist and audience was immediately palpable when the house lights went off and the cascading strobes and lasers filled the arena and Eilish appeared at center stage. The room turned a deep red hue as Eilish, donning all black with white sneakers and wearing a knee brace, bounced up and down during the opening notes of “bury a friend.”

“It’s been quite a week, it’s been a blur,” Eilish said early in her nearly two-hour set. “I won an Oscar!”

Fresh off her victory for Best Original Song (for “No Time to Die”) at the Academy Awards, Eilish said she was sick and performing on very little sleep, but still managed to pack a powerhouse performance for fans who waited two years to see her perform in the Bay Area.

The production was gargantuan. There was a giant projection screen, steep ramp, risers and every part of the stage seemed to light up, move, or have some other visual element. Eilish walked down a projected street, running all the way to the top of her steep stage on “NDA.”

Eilish was chatty with the audience, jumping from self-deprecation to serious commentary and non-sequitur hilarity.

“Does it smell kinda musty in here?” Eilish casually asked at one point. “I think I just have a sensitive nose.”

The singer was at her best when she was with her people, performing on the ramp that divided the crowd on the floor. Fans fed off of Eilish’s magnetic energy and screamed and sang along with the pop star all night long.

Songs like “you should see me in a crown” brought things to a fever pitch with frenetic energy. Eilish sat on a stool to perform a stellar version of “No Time To Die.”

After leading the crowd in a spirited rendition of “Happy Birthday” to her mom, she went off on a tangent, realizing what she’d forgotten to do earlier in the day.

“I woke up at like 1 p.m. and completely forgot to brush my teeth,” Eilish said, laughing. “That’s gross, no wonder it smells bad.”

It was a random aside, but made for a legitimately funny moment that Eilish called back to over the course of a three-song acoustic set.

She also kept a close eye on the pace of the show, asking attendees to go hard at times but take it easy during the slower songs.

“It’s OK to sit down here, grab some water, take a breath,” she said.

Two backing musicians, which included brother and collaborator Finneas, held down the rhythm section. Finneas is a multifaceted musician, singing backing vocals and playing bass, guitar, keys and percussion.

In the time it took the lights to dim, Billie Eilish had already rushed across to the other side of the floor to jump on a riser that swung the singer in circles and to the highest reaches of Chase Center. At times, it even seemed like the platform holding her up was moving at a solid clip, making the performance more daring.

Eilish returned to the main stage to carry home the show with some of her most anthemic songs, starting with the newer tracks “Getting Older” and “Lost Cause.” Much of the show consisted of songs from 2021’s Happier Than Ever, though there was plenty from her debut album. Eilish crammed in an impressive more than two dozen songs.

She saved her most high-impact songs for the end. Following a brief respite to catch her breath. Eilish spoke about fighting climate change and caring for others, before moving into “everything I wanted,” which at one point featured her singing to fans projected onto the massive screen.

The absolutely infections “bad guy” elicited exactly the response you’d expect, with plenty of carefree bouncing and singing along. But if you thought that song would bring the biggest reaction of the night, you’d be incorrect. Closer “Happier Than Ever” had fans singing as loud as they had all night, at times almost overwhelming the soft-spoken Billie Eilish. The song closed on a masterful note, with a grunge-tinged outro and lights flashing in all directions, providing a compelling and urgent moment.

Rapper Duckwrth opened the concert and successfully warmed up the crowd. A little bit Outkast and a little bit Kendrick Lamar, Duckwrth brought a versatile sound to the stage. Donning a kilt and tall white socks, the rapper performed an aggressive set.

“San Francisco was the first city where I ever wore a skirt, so I figured I’d wear a kilt tonight,” he said.

He was backed up by an impressive four-member band and a trio of backup singers, who helped bring each song to life. The rapper even brought a casual conversational appeal in talking with both the crowd and his own band.

“You want to play that new song we were trying out earlier in the week?” the rapper asked at one point, seemingly changing up the setlist on the fly.
