“Boston, Boston, Boston.” It felt like the whole city was listening to Lorde as she rolled our name around her mouth. She strutted fearlessly across the stage, her raspy voice booming out of the microphone.

At Lorde’s April 12 performance on her Solar Power tour, the Boch Center Wang Theatre in downtown Boston was filled with 3,500 screaming fans. For such a well-known singer, that number might seem low. But Lorde, who has struggled with stage fright, prefers a more intimate venue to a massive stadium like TD Garden, where many mainstream artists perform during the Boston leg of their tours. For Lorde’s two-night stay in Boston, she booked the Wang Theatre and easily sold out both nights.

The intimacy of the performance was unique and powerful. At several moments, Lorde spoke vulnerably to the audience like a conversation between friends.

“I know I have a lot of big feelings that I am working through,” she said, inviting the audience to dance it out with her.

The 25 year old artist sang over twenty songs and performed for almost two hours without stopping. About half of the show was songs from her groundbreaking newest album, “Solar Power,” which was released in August 2021. The other half was popular older songs from Lorde’s previous albums.

The concert had a great mix of upbeat dancing songs and slower, more melancholy ones. She opened with the calm and short “Leader of a New Regime” off the new album, and then jumped into “Homemade Dynamite,” a fiery and explosive anthem from her 2017 record “Melodrama.” At some moments, Lorde would sit down on the rotating staircase in the middle of the simple set and belt out emotional ballads including “Liability” and “Ribs.” A few minutes later, she would be jumping up and down in the corner of the stage screaming a song like “Green Light” or “The Path.”

The concert was flawless save one microphone malfunction in the second song. I was captivated by Lorde’s every erratic dance move and impressive note. Her raw and vulnerable confidence held everyone’s attention.

At one point, she explained that her frenetic dance moves are her way of expressing the emotions she feels from her songs. If any other person on the planet were up there dancing like she was, I might’ve questioned it. But with Lorde, I found it impossible to doubt any of her decisions. Instead, I was mesmerized by these idiosyncratic movements, whether she was marching around the stage or waving her arms wildly.

One of the many highlights was when Lorde spontaneously decided to perform “Big Star.” She explained that she loves Boston and felt like it’s a good place to try a new way of performing one of her songs.

In “Stoned at the Nail Salon,” one of the most popular and moving songs on “Solar Power,” Lorde sings that “all the music you loved at sixteen you’ll grow out of.” But, after this concert, I don’t think I’ll ever grow out of my obsession with Lorde.
