Shane Boose says that, if a piece of music can be described as “alternative” or “indie,” he’s probably going to enjoy it. “My favorite band of all time is Radiohead,” Boose, who records as Sombr, tells Billboard. “And I’m a big fan of Jeff Buckley, Phoebe Bridgers, The 1975. I listen to a ton of alternative music — it’s my genre.”
Those influences help explain why Sombr’s two fast-rising hit singles, “Back to Friends” and “Undressed,” have not only exploded on streaming services as crossover pop hits, but have also minted the 19-year-old singer-songwriter at rock and alternative platforms that have been starving for fresh new talent. On this week’s Hot 100, “Back to Friends” leaps up 14 spots to a new peak of No. 56, while “Undressed” jumps 12 spots to No. 84; meanwhile, “Back to Friends” hits the top 10 of the Hot Rock & Alternative Songs chart for the first time, bumping up to No. 9 with “Undressed” close behind at No. 13.
Sombr has been on the road over the past few weeks opening for Daniel Seavey in the U.S. — watching each day as his streaming totals grow (through Apr. 17, “Back to Friends” had earned 40.7 million official on-demand streams, while “Undressed” had earned 19.5 million streams, according to Luminate) and his crowd sizes swell.
“They 100 percent break my brain,” he says of the streaming totals. As for the crowds, “You don’t usually get to see it happening in real time, increasing every show, but being able to see that has just put it into perspective. When I’ve had moments in previous years, they’ve never been like this. And I’ve never gotten to visualize it while it was happening in real time.”
Boose grew up on the Lower East Side and attended the prestigious LaGuardia High School, where he studied vocals while tinkering with GarageBand and Logic in his bedroom. “I made the first few songs in a more shoegaze vein, and most of those songs aren’t even out,” he says. “And then I made the song ‘Caroline’ after listening to Bon Iver’s For Emma, Forever Ago album, and I’d like to think that’s the first good song I ever made.”
Released in mid-2022, “Caroline” is indeed a sparse, wrenched folk song that Boose posted to TikTok before going to bed one night, and woke up the next morning to find thousands of reactions. He dropped out of high school, signed a deal with Warner Records in early 2023, then spent roughly two years trying to get lightning to strike for a second time with a string of singles, to little avail.
Sombr, who still writes and produces all of his songs, says that he never got impatient while awaiting his breakthrough following his major label signing. “I was just making music,” he says, “and I’m a really hard worker. I like to think that, if you really put in the hours and manifest what you want, it will happen.” On the day that he made “Back to Friends” in his bedroom, he played the finished chorus back, and felt that, with this song, it was finally going to happen for him.
Released last December, “Back to Friends” is a swirl of shakers, dramatic piano chords, fuzzed-out vocals full of post-hookup anxieties and harmonies that lob out rhetorical questions on the chorus. Along with March’s “Undressed,” a ghostly warble-along with an equally outsized chorus, Sombr has reinvented his sound over the course of two songs, moving on from the hushed singles released post-“Caroline” and toward slick, slightly swaggering alt-pop.
“I think they gave me a platform to make more upbeat music,” he says of the two tracks. “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.”
After wrapping up his tour with Seavey last week, Sombr will next hit the road with Nessa Barrett, joining for a month-long European run that kicks off on May 26 in Dublin. Earlier this week, however, Sombr announced a fall headlining tour across North America that will start on Sept. 30 — and thanks to the surging momentum from “Back to Friends” and “Undressed,” pre-sale tickets apparently sold out within seconds. (“The response has been insane,” Sombr posted on Instagram. “I hear you all. I am working on upgrades and new dates. Stay posted.”)
And while Sombr says that a proper debut album is “definitely on the horizon,” he’s trying to savor this singular moment. “The last show in New York, it was the loudest it’s ever been, and I got it in the pit,” he says before letting out a quick laugh. “It’s getting wild, and I love it. It’s all I’ve ever wanted.”
