Yumi Arai

A twilight reverie painted in deep blue light, Cobalt Hour moves with the quiet electricity of a city exhaling at dusk.

Yumi Arai’s voice drifts like smoke over warm chords and soft, unfolding rhythms—melodies shaped by memory, motion, and the glow of neon on wet pavement.

Each track is a window into a fleeting moment: tender, cinematic, and tinged with a gentle ache.

Cobalt Hour is pop rendered as atmosphere, as emotion, as a quiet pulse in the chest—an album that lingers long after darkness settles, colouring the night in shades of luminous blue.
