Untie

VIVIZ arrived as a smaller, tighter unit than their GFRIEND days, and "Untie" announces that transition with a surge of retro-funk confidence. Shimmering synth stabs and a rubbery bass groove anchor the track in early 1980s disco-pop territory, while the production stays crisp and modern — the vintage warmth is a flavor, not a costume. The tempo sits at a buoyant mid-120s BPM, never frantic, always propulsive, leaving room for the three voices to breathe and interlock. Eunha, SinB, and Umji trade lines with a lightness that feels genuinely playful rather than manufactured — there is a specific kind of joy in a group that has nothing left to prove. Lyrically, the song orbits liberation: the shedding of whatever had been holding someone back, done not with rage but with a head toss and a grin. The chorus opens up into something almost euphoric, the kind of moment you'd catch at a late-afternoon outdoor stage when the crowd is loose and the light is going golden. "Untie" is for a Saturday when you have nowhere to be, played in a car with the windows down, belonging to the exact crossroads where K-pop girl group craftsmanship meets the kind of groove that makes your shoulders move before your brain decides to let them.
