The last time Alice Phoebe Lou was in Boston, she opened three sold-out nights at Roadrunner for Clairo. On Saturday night, the singer took the stage at the Berklee Performance Center for the first American show of her “Oblivion” tour.

I remember being in that Clairo audience, seeing the crowd shake out of their unbecoming push-to-the-barricade mindset to the soundtrack of Lou’s bewitching set. This time around, the crowd was there just for her. And they were all seated.

Lou started making music as a busker in Berlin and has since released six albums independently. Her sound blends indie-folk with jazz and electronic elements, but her most recent album, “Oblivion,” is a dreamscape backed by no-frills piano and guitar.

Unlike her past shows, she was not accompanied by a band, and instead rotated between four instruments in a stripped-back, intimate set. 

“I’ve always had a bit of a complex feeling like I’m not enough without the band, you know, without the backing, without more,” she said while on stage. “It’s really nice to come up here and feel like enough.”

As Lou sat down at the piano, she chuckled to herself. “I’m almost embarrassed playing piano at Berklee, of all places.” 

But if she was embarrassed, she didn’t show it. Her voice had a discernible confidence to it. Joined by only one instrument at a time, she moved smoothly between her more ballad-like songs at the piano and her more buoyant tracks.

Thoughtfully striking out the intro to “Oblivion” on the keys of Berklee’s grand piano, Lou sang, “There’s no need to run / When I’m flying into oblivion.” 

The song feels like Lou is traveling through a maze, and her intense focus on the piano in front of her suggested that she was not just racing towards the end, but genuinely enjoying each twist and turn. 

“When I opened my eyes / She was there and her skin was golden / I took her hands and said / I’m happy to be back with you,” she sang, peacefully concluding the song. 

Lou’s lyrics are already contemplative, and playing in front of the seated audience seemed to calm something in her. 

Halfway through the set, she beamed, teasing the spellbound audience with an unreleased song she said she had never performed before. “Why not?” she concluded before treating the Boston crowd to yet another earnest musing. After that, she played “Lately,” from her 2023 release “Shelter,” which she said was her dad’s favorite song of hers.

If Lou was experimenting, then the Berklee Performance Center had turned into a petri dish, and she was gracefully presenting her cultures for the sponge-like audience.

“Oblivion” is itself a stripped down album, but the lack of band didn’t impede the rest of Lou’s setlist.

“Touch,” from her 2021 release “Glow,” has an instrumental depth to it, which Lou recreated live with an omnichord. Cascading harp-like notes erupted from the little white machine as opener John Andrews returned to the stage, strumming a guitar behind Lou.

Still, her vocals shone through as she sang “I wanna give you all I’ve got / Until my body begins to rot / You’ve been hangin’ out in my head / I’ve been imaginin’ you in my bed.”

Whether or not her clear and confident vocals can be attributed to the genius sound techs at Berklee is unclear to me at this time. I am okay with either possibility.

She stuck with the omichord for a few more songs, until lifting the acoustic strap back over her shoulders to close the show out. 

Lou told the crowd we would know this next one, and to sing along. Within just one strum, the crowd exhaled a sigh of elation — it was Neil Young’s “Harvest Moon.”

With each chorus, “I want to see you dance again / Because I’m still in love with you / On this harvest moon,” the crowd became more confident, eventually matching Lou word for word.

After the jaunty “Open My Door,” which was the only song of the night to have a backing track — Lou called it karaoke — she stayed right where she was, and said “This is my encore, I’m a diva. I won’t go away. It’s been lovely oversharing with you all.”

With that, she closed the night with arguably her biggest hit, “Witches.” “I’m one of those witches, babe,” she repeated throughout the song. When she finished, the spell she had cast on the audience broke, but the influence of Lou’s enchanting set was sure to last far beyond the final song.
