He posted a song to TikTok one night, went to sleep a high school junior, and woke up to find every record label in his inbox. That was 2022. By 2025, sombr had a billion streams, a sold-out world tour, a Grammy nomination, and a co-sign from Taylor Swift. He is twenty years old. He has been working toward this since he was eleven.
Lower East Side, Before It Was Cool Again
Shane Michael Boose was born on July 5, 2005, in New York City, and grew up on the Lower East Side — the neighborhood now known as Dimes Square — with parents who worked in events and communications. A tattoo on the knuckles of his left hand reads “LES.” “When I was growing up there in the 2010s, Dimes was definitely not a cool area,” he has said. This is the kind of detail that will age interestingly — the kid who grew up in the neighborhood before the aesthetes arrived, who absorbed the city as texture rather than identity brand.
His father was a former musician in a New York City performance-art rock band. His mother worked in entertainment communications. Boose was introduced to GarageBand at the end of elementary school and began experimenting with layering tracks and harmonies. In middle school, he advanced to Logic Pro X and began learning production techniques through online tutorials. This is the curriculum of a generation that grew up treating software as an instrument — not as a shortcut but as the thing itself, the same way earlier generations grew up treating guitars or pianos as the primary site of musical discovery.
He attended LaGuardia High School — the U.S.’s most prestigious public school for the arts, which has produced everyone from Jennifer Aniston to Timothée Chalamet and Slick Rick — as a vocal major. “Everyone was very supportive of each other,” he has said of the environment. “We were all working towards the same thing.” Then, after a beat: “Maybe it was a fashion competition.”
He was at LaGuardia, studying vocals, sneaking Logic Pro sessions during lunch, and writing songs that nobody outside his bedroom was hearing yet, when the turn came.
A Name Built From Initials and a Bad Feeling
Boose released his debut single, “Nothing Left to Say,” in October 2021, adopting the stage name sombr upon release. The name incorporated his initials — SMB — and reflected his emotional state at the time. He has explained it simply: “To be quite honest, I was going through a rough part of my life when I released my first single.”
The lowercase styling matters more than it might seem. sombr — never capitalized — carries the visual suggestion of something slightly diminished, slightly under the radar, which is precisely the aesthetic he was cultivating: big feelings delivered in a small room, intended for whoever happened to find them. For the first year, almost nobody did.
The Night “Caroline” Changed Everything
In 2022, he made a song called “Caroline” after listening obsessively to Bon Iver’s For Emma, Forever Ago. “I’d like to think that’s the first good song I ever made,” he has said. It is a sparse, wrenched folk song — the kind of thing that sounds like it was recorded in one take because the emotion wouldn’t survive a second one. He posted it to TikTok before going to bed.
“I went to bed just a normal high school kid and I woke up the next day, it’s viral. Literally the next day,” he told Variety. “Every record label is in my inbox.” When he told his father what was happening, “he was like, ‘I don’t believe you.'”
He had been getting bullied at school for doing music. When “Caroline” worked, he felt some of those same people start hating him. Within days he was on a plane to Los Angeles. He dropped out of his junior year. His mother was not too happy. His father was more supportive. Boose’s position was clear: “This is all I wanted to do. Why should I go to school and delay the whole thing when it’s happening now?”
In early 2023, he signed with Warner Records. That same year, legendary A&R man and producer Tony Berg — whose recent work includes Phoebe Bridgers’ Punisher and Lizzy McAlpine — became a close collaborator. Berg is the kind of producer who does not sand down an artist’s rough edges so much as help them understand which edges are structural. The EP that followed, In Another Life, was the result: a small-scale demonstration of what the bedroom recordings had been pointing toward.
Then came two years of relative quiet. Singles that didn’t catch. Shows in 200-cap clubs that weren’t selling out. He says he never got impatient. “I was playing 200-cap clubs that weren’t selling out,” he has said, describing the period with something closer to acceptance than frustration. He kept writing alone.
“Back to Friends,” and the Feeling He Needed to Name
“Back to Friends” was released on December 27, 2024. Boose started building it not from chords or a melody but from a drum groove in Addictive Drums, letting the rhythm establish the song’s emotional temperature before anything else existed.
The premise of the song is almost aggressively specific — the aftermath of a relationship that ended, but specifically the part where you’re supposed to just be friends again, and every time you look at each other you both know that’s not entirely true. “I think it’s a universal topic, but I think with the chorus, I found a unique way of saying it,” he told Variety. The chorus in question — “How can we go back to being friends / How can you look at me and pretend / I’m someone you never met?” — is direct enough to feel obvious and precise enough to feel like something you haven’t quite heard said that way before.
The song went viral on TikTok in early 2025 and topped the Spotify Global Weekly Chart in July. It became his first entry on both the Billboard Global 200 and the Hot 100, peaking at numbers five and ten respectively, while reaching number one on Alternative Airplay and Hot Rock & Alternative Songs. It eventually surpassed one billion streams on Spotify on October 20, 2025.
“Undressed” followed in March 2025, experiencing similar virality — a ghostly, outsized chorus built around watching an ex move on from across the train tracks. Together, the two songs accumulated 2.5 billion combined streams on Spotify and a co-sign from Taylor Swift, who shared the songs unprompted. That kind of endorsement is either impossible to engineer or the natural outcome of making something undeniable — probably both.
Sombr has said the success shifted what he was willing to attempt sonically: “Before ‘Back to Friends,’ all my music was very ballad-y — there was nothing with a beat. I was so tired of that. I feel like this is a lot more free, as far as the music I want to create. And I wanted my show to be more exciting. I didn’t want to just do ballads forever.”
I Barely Know Her: The Debut on Its Own Terms
I Barely Know Her was released on August 22, 2025, through Warner Records and Boose’s own imprint, SMB. Written entirely by Boose and co-produced with Tony Berg, the ten-track album is structured as a breakup record, exploring heartbreak, longing, and emotional self-reflection, with several songs drawing on New York City imagery to contrast romanticized memory with everyday reality.
The album’s opener, “Crushing,” opens with distorted, almost scream-like vocals before the chorus breaks through — sombr’s characteristic punchy bass and piano, simple but strong drum backing, a butterfly-effect narrative about mourning the future you didn’t get to have. It is a disorienting entry point, and deliberately so: the album announces from the first thirty seconds that it will not be tidy.
“Canal Street,” by contrast, is as calm as the album gets — an acoustic guitar ballad, a song about mainlining cigarettes to remember the smell of someone who left, with some of the finest storytelling on the record. “12 to 12,” the fourth single, steers toward disco-inflected pop — heavy beats, swirling piano arpeggios, a glossy banger that somehow contains the same emotional wreckage as the slower tracks.
Variety praised the album as a triumphant arrival, noting that sombr “sounds like he’s stepped out of the bedroom and onto the big stage, bursting with ideas and equipped with the skills to see them through.” The review credited Tony Berg with adding fullness and scope to the established sound, while emphasizing that the album — written entirely by Boose, who also plays guitar, keyboards, bass, and drums across most tracks — remains singular in ushering elements of 2010s indie rock into a pop arena.
The critical response was not unanimous in its enthusiasm. NME praised I Barely Know Her as a smart and cathartic reimagining of the breakup album, framing it as a leap from his viral bedroom-pop roots into slick, festival-ready territory. The Needle Drop, by contrast, was more skeptical — acknowledging Boose as a passionate and talented vocalist while suggesting the album goes “decently in a lot of different directions” without yet excelling at any of them, calling it a useful starting point rather than a defining statement. The divide maps onto a genuine tension in the record: it is a debut that is clearly good and clearly not yet quite finished becoming what it wants to be. These are not contradictions. They are just what twenty looks like.
Commercially, the album reached the top five in Australia, the Czech Republic, Finland, Lithuania, New Zealand, Norway, Scotland, and Sweden, and charted within the top ten in twelve other countries, including the United States and the United Kingdom.
The Question of Sole Authorship
There is one detail about I Barely Know Her that matters more than any chart position, and it is this: across all ten tracks, sombr is the only credited songwriter — a relatively uncommon feat that speaks to his desire to stay in control of his own creative vision.
He has described his writing process as resembling therapy, saying he starts with raw, unfiltered feelings and then builds the music around them. For him, lyrics aren’t polished first — they’re excavated. He has also said he cannot write with other people in the room: the vulnerability required to start a song honestly is incompatible, for him, with an audience.
“All I want is for my best song to be as good as Jeff Buckley’s worst,” he told i-D. That is either an absurdly high bar or the only honest answer to the question of what he is aiming for — the kind of aspiration that can sustain a career precisely because it is impossible to fully reach.
His influences, by his own description, run from Radiohead to Phoebe Bridgers to The 1975 to the Rolling Stones to Prince — a range that includes some of the most technically demanding and emotionally committed artists of the past sixty years. He is not embarrassed by the ambition. He wears it the way you wear something that fits.
What Twenty Sounds Like
He told i-D: “This is corny to say, but it’s like my music got me through life.” Said at twenty, that claim is both precocious and exactly right. He is not someone for whom music is a career that happened to coincide with his youth. He is someone for whom music is the thing his youth organized itself around — the reason for the LaGuardia commute, the GarageBand sessions during lunch, the TikTok post before bed, the decision to get on a plane.
He slept through the announcement of his Grammy nomination and woke up to a flood of messages. He was still playing modest shows when he wrote the songs that eventually put him in the conversation for Best New Artist. “I was playing 200-cap clubs that weren’t selling out,” he said. “Why am I even expecting that to happen?”
The 2026 AMA New Artist of the Year nomination arrives at a twenty-year-old who is, by any honest accounting, still mid-sentence. The debut album is ten tracks and thirty-something minutes of a very specific kind of heartbreak, recorded entirely by one person, sold to more than a billion listeners who apparently needed to hear it said exactly that way. What comes next is the interesting question — what happens when the boy who built his whole aesthetic from romantic loss tries to make a second record, now that the world is watching and the room is no longer just his bedroom.
He has said he wants to headline Madison Square Garden. He has said he wants to collaborate with Billie Eilish. He has also said, with the particular clarity of someone who has thought about mortality more than most teenagers: “I want to die and have people be like, ‘Wow, his music was great. I wish he didn’t die.'”
That is a twenty-year-old’s way of saying: I want the music to outlast everything else. Which is, historically speaking, the only ambition in this industry that ever actually works.
This concludes the 2026 AMA New Artist of the Year series. Profiles covered: KATSEYE, Ella Langley, Alex Warren, Leon Thomas, Olivia Dean, sombr.
