Glassio’s latest single, “Heartstrings” glows with the bittersweet euphoria of new love, anchored by a sun-drenched, upbeat indie-pop groove that feels tailor-made for summer road trips. Born from a moment of inspiration while working behind the counter at London’s Banquet Records, Sam R.’s spontaneous vocal line over a Blossoms track eventually evolved into this infectious anthem.

Sam R., the voice behind Glassio, has been crafting emotional, genre-blending indie-pop for years, pulling from his unique background growing up between the Middle East and California. His music has been featured in various shows like Locke & Key and films like Don’t Make Me Go, and he’s built a loyal global fanbase with his dreamy sound and heartfelt lyrics.
