Claire Rosinkranz

Claire Rosinkranz (born January 2, 2004) is an American singer-songwriter from Southern California whose bedroom-written single “Backyard Boy” became one of the defining TikTok-era breakout songs of 2020, propelling a then-16-year-old homeschooled ballet dropout to a Republic Records deal, an RIAA certification, and an eventual arena stage opening for Maroon 5. Nearly six years later she released her sophomore album My Lover on 10K Projects/Atlantic Records, following a health crisis that reshaped both her music and her public voice.

Early Life & Family

Claire Rosinkranz was born January 2, 2004, and grew up in Southern California, with sources placing her early years in Agoura Hills and Los Angeles. She was homeschooled, a structure that let her devote unusual hours in childhood to two disciplines at once: ballet, which she trained in seriously enough to consider as a career path, and songwriting, which she had been doing since roughly age eight. She has described a specific turning point around age eleven when she felt she had received a clear answer about which path to choose, and picked music.

Music was, in a sense, the family business before it was hers. Her father, Ragnar Rosinkranz, is an Icelandic-born composer, producer, and violinist who has scored television and film work and written jingles for commercial work; Claire helped him brainstorm melodies and lyrics for that jingle work as a child, an informal songwriting apprenticeship that predates her own recording career. Ragnar has produced or executive-produced virtually all of her music since, from the earliest bedroom recordings through her 2026 album. Her paternal grandmother was an Icelandic opera singer, giving Rosinkranz a direct classical and compositional lineage unusual for an artist who broke through via TikTok. She has a sister, Ellie, and has spoken about having synesthesia, meaning sound involuntarily triggers her perception of shapes and colors, a trait she has connected to her songwriting instincts in interviews.

The “Backyard Boy” Breakout

In June 2020, during the early months of COVID-19 quarantine, 16-year-old Rosinkranz independently released a five-song EP called BeVerly Hills BoYfRiEnd, written and largely self- and father-produced. Its centerpiece, “Backyard Boy,” is a jangly, conversational song about an unrequited crush, delivered in Rosinkranz’s warm, diary-style voice. She was staying at a friend’s house in Oregon at the time and had deleted TikTok from her phone, so by her own account she did not immediately register that the song was taking off; she found out because friends started texting her about it.

The numbers, once she looked, were startling for an unsigned teenager: the song inspired well over 2.6 million TikTok video recreations, at one point reportedly outpacing Olivia Rodrigo’s “drivers license” at a comparable early stage, and racked up more than 50 to 70 million Spotify streams within months. It hit number one on Spotify’s Global and U.S. Viral 50 charts. That organic streaming performance, rather than any label campaign, is what brought Rosinkranz a record deal at age 16 with Slowplay, a boutique imprint of Republic Records under Universal Music Group. Republic issued a wider release of BeVerly Hills BoYfRiEnd in August 2020, and the song was later given a remix featuring Thomas LaRosa’s frequent collaborator category peers in the bedroom-pop scene of that moment, though the officially released remix partner was singer-songwriter Jeremy Zucker.

Early Catalog: EPs, Singles, First Label Era

Rosinkranz had actually released music before her breakout, including “Best Friend” and “Sugar Water” in 2019, but it was “Backyard Boy” that defined her. In 2021, now signed to Republic, she released a second EP, 6 of a Billion, which included “Frankenstein,” co-written and produced with M-Phazes, Chelsea Lena, and Lexi Jayde as a loose reinterpretation of The Cardigans’ 1996 hit “Lovefool,” and “Boy In a Billion.” That year she also released “change ur mind” with Sarcastic Sounds and Clinton Kane, the paired singles “Real Life” and “Parking Lot,” and contributed “don’t miss me” to the soundtrack of the film The Hating Game. That same year, “Backyard Boy” won the inaugural “Best Breakthrough Song” at the 2021 MTV “Trending: VMAs,” a category TikTok and MTV created specifically to honor TikTok-driven music breakouts, and both Billboard and The New York Times named it among the best songs of 2020.

Through 2022 Rosinkranz released a steady run of standalone singles, including “i h8 that i still feel bad for u,” “stuck on us” with Aidan Bissett, and “i’m too pretty for this,” while touring as a support act for Alec Benjamin and Dermot Kennedy and building a headline club circuit of her own. In 2022 she was also nominated for “Social Star” at the iHeartRadio Music Awards.

Just Because and the Growing-Up Years

Rosinkranz’s debut studio album, Just Because, arrived on Slowplay/Republic on October 6, 2023, a 13-track record that closed out the first phase of her career. Its lead single, “123,” was co-written with production trio Captain Cuts (Ben Berger, Ryan Rabin, and Andrew Wessen) and became a Gen Z break-up anthem of that summer, according to Universal Music Canada’s own framing of the release. Other album tracks included “Sad in Hawaii,” “Never Goes Away” (produced by Elie Rizk), “Screw Time” (produced by Stint, the production alias of Ajay Bhattacharyya), “Pools and Palm Trees,” “Wes Anderson,” “Swinging at the Stars,” and album cuts “Dreamer,” “Banksy,” “Gum,” “Polarized,” “Jupiter,” and “Mess.” The Guardian profiled her around the album’s release, comparing her diary-style, coming-of-age confessional songwriting to Olivia Rodrigo’s. That same year she performed at Lollapalooza, Austin City Limits, and Life Is Beautiful, and was featured on Chicago electronic duo Louis the Child’s single “Walls.”

Sonic Identity

Rosinkranz has described her own sound as “alternative blues-pop,” while labels and press have variously filed her under indie-pop, lo-fi pop, bedroom-pop, and electro-pop. She cites The Beatles’ Help!, Frank Ocean, and Jack Johnson, a family listening staple, as formative influences, alongside contemporaries like BENEE, Bruno Major, and Still Woozy. Her signature is a warm, conversational vocal delivery paired with wry, often self-deprecating lyrics about crushes, friendship, and family, set against gleeful, jangly guitars and chantable, lo-fi-tinged choruses. She writes almost every song alone first before bringing a small trusted circle, principally her father Ragnar Rosinkranz, producer Oliver “Junior” Frid, and occasionally songwriter Eddie Benjamin, into the room to finish it. For the My Lover era, she has leaned on a recurring visual and thematic vocabulary of gardens, horses, ballet, and the ocean, symbols she has explicitly tied in interviews to ideas of duality: growth against decay, delicacy against strength.

Chart Performance & Certifications

“Backyard Boy” remains Rosinkranz’s career-defining chart and streaming story. Beyond its number-one runs on Spotify’s Viral 50 charts, it peaked at number 97 in the United Kingdom and number 48 in Ireland on official national charts, and was certified Silver by the BPI in the UK. In the United States, the RIAA’s Gold & Platinum database lists a certification for the song dated March 17, 2022; label and press materials described it as Gold-certified through 2023 and 2024, and by 2025 and 2026 press cycles it was being described as Platinum, indicating an upgrade as cumulative streaming totals grew. By 2024 to 2026, press materials cited her catalog, anchored by that single song, as having crossed one billion global streams. As of June 2026, a college-press roundup put her at roughly three million monthly Spotify listeners.

Health Crisis, Faith & the 10K Projects Move

By mid-2024, Rosinkranz had signed with C3 Management under manager Russell Baltera, a firm that would go on to launch a publishing arm, C3 Publishing, with WCM in the same period. In March 2025 she performed at South by Southwest as part of a C3 Management and Do512 showcase at Stubb’s Bar-B-Q in Austin, alongside label mates including Band of Horses, Jack’s Mannequin, Yoke Lore, The Criticals, and The Droptines, previewing then-unreleased songs including “Jaden,” “Lucy,” and “Funeral,” and publicly voicing frustration on TikTok about the gap since her last release.

That frustration had a cause beyond ordinary label logistics. At some point in 2025 Rosinkranz experienced what she has since described as a serious health crash while touring, leading to an extended period of recovery. In 2026 interviews, including an in-depth March 2026 conversation with Nyota Magazine, she discussed how that period reshaped both her physical routine and her songwriting, and connected it to her Christian faith, which she has described as central to her creative process. Her January 2026 single “Chronic” is directly about the chronic-illness experience that grew out of that crash.

Commercially, the same period marked a label change. In July 2025 Rosinkranz moved from Republic/Slowplay, her home since 2020, to 10K Projects and Atlantic Records, part of Warner Music Group, releasing “Jayden” and “Lucy” as her first new-label singles. 10K Projects is the same label that, per its own billing, is built around Artemas’ sensibility and also carries Arden Jones on its roster, placing Rosinkranz's second act on an imprint already known in the wider pop landscape for signing artists off streaming-native momentum rather than traditional radio setups.

My Lover (2026)

Rosinkranz’s sophomore album, My Lover, was released February 13, 2026, on 10K Projects/Atlantic, produced primarily by Oliver Frid and executive-produced by her father, Ragnar Rosinkranz. The album followed a rollout of singles: “Jayden” and “Lucy” in July 2025 (the latter co-produced with Frid, Ragnar Rosinkranz, and Chelsea Balan), “Dancer” in August 2025, “Crazy Bitch Song” in September 2025 ahead of her Maroon 5 tour dates, “Kiss” in October 2025 mid-tour, “Chronic” in January 2026, and focus track “City,” which she performed on NBC’s TODAY show on February 17, 2026. A September 2025 press item had referred to the then-unfinished project under the working title “The Garden” before it was ultimately released as My Lover.

Tours: Maroon 5, Alex Warren & Headline Runs

The single biggest live milestone in Rosinkranz’s career came in the fall of 2025, when she was announced as the opening act for Maroon 5’s Love Is Like World Tour on the same day the tour itself was unveiled. The North American leg ran October 6 through November 25, 2025, twenty-three dates opening with her first-ever arena show at what is now Mortgage Matchup Center in Phoenix, Arizona, and continuing through the Kia Forum in Inglewood, Chase Center in San Francisco, two nights at Madison Square Garden in New York, TD Garden in Boston, and a closing date at Little Caesars Arena in Detroit. She also played an additional New Year’s Eve date with the tour at Atlantis, The Palm in Dubai on December 31, 2025. Her sets ran roughly 30 minutes ahead of Maroon 5’s approximately two-hour headline show, and her management publicly celebrated the booking, writing on Instagram that they were “so proud of our client @clairerosinkranz for opening for @maroon5 on their Love Is Like Tour.”

Before the Maroon 5 run, Rosinkranz had built her live resume as a support act for Alec Benjamin and Dermot Kennedy across 2021 to 2023, alongside her own headline club shows and festival sets at Lollapalooza, Austin City Limits, and Life Is Beautiful in 2023. After the Maroon 5 tour and the release of My Lover, she opened for Alex Warren’s European arena tour from April 4 through May 7, 2026, stopping in Düsseldorf, the Netherlands, France, Germany, and the UK, and closing at Dublin’s 3Arena. From late April through early June 2026 she headlined her own run, the My Lover Tour, across North American clubs and theaters including Seattle, Portland, San Francisco, Los Angeles, Phoenix, Denver, Minneapolis, Chicago, Columbus, New York’s Webster Hall, Boston, Philadelphia, Washington D.C., and Toronto. Later in 2026 she is slated to return to the festival circuit with Lollapalooza and a reported Austin City Limits booking.

Collaborators, Label & Team

Rosinkranz’s creative team has stayed remarkably consistent across two label eras. Her father, Ragnar Rosinkranz, has produced or executive-produced nearly her entire catalog, from “Backyard Boy” through My Lover. Producer Oliver “Junior” Frid, whose credits include work with Ariana Grande, Dua Lipa, and Little Mix, took on a central production role for the My Lover era, and songwriter Eddie Benjamin has contributed to select songs, including “Home.” Across her catalog she has worked with a wide range of collaborators: Jeremy Zucker on the “Backyard Boy” remix; ROLE MODEL and Hauskey on the BeVerly Hills BoYfRiEnd remixes; M-Phazes, Chelsea Lena, and Lexi Jayde on “Frankenstein”; Clinton Kane and Sarcastic Sounds on “change ur mind”; Aidan Bissett on “stuck on us”; Captain Cuts on “123”; and producers Elie Rizk, Sammy Witte, Joe Janiak, Stint, Paul Meany, Julian Bunetta, AfterHrs, and Paul Phamous across Just Because. Louis the Child featured her on their 2023 single “Walls.” For My Lover-era tracks like “Lucy” and “Kiss,” credits also include Chelsea Balan, Summer Davis, and Austin Corona.

On the business side, Rosinkranz signed independently before any label involvement, self-releasing her 2020 breakout EP. Her organic streaming numbers led to a deal with Slowplay, a boutique imprint of Republic Records under Universal Music Group, at age 16, which released her music through 2024. In mid-2025 she moved to 10K Projects and Atlantic Records under Warner Music Group, the home for her My Lover era. She is managed by C3 Management under Russell Baltera and booked by Creative Artists Agency (CAA). Songwriting credit metadata on singles like “Kiss” shows a co-publishing entity called Maison Arts Publishing Company alongside Kobalt, suggesting Kobalt administers at least part of her catalog, though no dedicated exclusive publishing deal has been publicly announced.

Further Reading

Claire Rosinkranz’s story sits at the intersection of two distinct pop-music moments: the TikTok-driven bedroom-pop wave of 2020, which also produced breakout peers across the scene, and the 2025 to 2026 wave of streaming-era artists moving onto 10K Projects, the label associated with Artemas and Arden Jones. Readers interested in the broader ecosystem of viral-to-major-label pop artists from this period may also find relevant context in entries on Isabel LaRosa and Nessa Barrett, both of whom followed comparable paths from independent virality to major-label deals in the same Los Angeles pop landscape.
