Shane Michael Boose, known professionally as Sombr, is an American indie-rock singer-songwriter and producer who transitioned from a bedroom musician to a global breakout star. He first gained industry attention with the 2022 viral single "Caroline," leading him to leave the prestigious LaGuardia High School to pursue a career that has since defined the "alt-pop" sound of the mid-2020s. By 2025, his self-produced tracks "Back to Friends" and "Undressed" concurrently dominated the Billboard Hot 100, earning him a reputation for blending raw, lo-fi textures with hauntingly vulnerable storytelling.

In August 2025, Sombr released his debut studio album, I Barely Know Her, which debuted in the top ten of the Billboard 200 and featured the disco-infused hit "12 to 12." His meteoric rise continued into early 2026 with the release of the guitar-driven single "Homewrecker" and a performance at the 68th Grammy Awards, where he was nominated for Best New Artist. With over 80 million monthly listeners and a dedicated Gen Z following, Sombr remains a pivotal figure in the modern indie-rock revival.
