Glassio’s 'Heartstrings' Is a Summer Flashback You’ll Want to Replay

“Heartstrings” sounds like summer nostalgia on loop. Glassio, the indie-disco brainchild of Sam R., just dropped a shimmering new single that delivers everything we love about his vibe: melancholy-tinged lyrics over sunlit synths, addictive rhythms, and a head full of daydreams.

The song’s got that perfect "driving with the windows down" energy. Picture Ferris wheels, melting cotton candy, and some mid-2000s NYC cool—the kind of sonic fusion you’d get if Blondie shared a studio with The Drums and snuck in a few tears between dance breaks. There’s an effortless charisma here that makes it feel classic, even on first listen.

Glassio’s been riding a steady wave since 2024’s SPIN-lauded “Atlantic City,” and “Heartstrings” proves he’s not slowing down anytime soon. This track feels like a fun house mirror—reflecting both the glow and the ache of love’s early chaos.

Play it loud, play it often—just don’t be surprised if you end up catching feelings.
