Costaine - If You Only Knew (Official Audio)

Born and raised in the neon sprawl of Hong Kong, Costaine crafts instrumental synthwave that channels the city's contradictions — ancient temples wedged between skyscrapers, cha chaan teng steam rising past LED billboards, the hum of trams beneath towering glass. Raised on a diet of '80s Cantopop cassettes inherited from his parents and a growing obsession with vintage analog synthesizers found in Sham Shui Po's electronics markets, he began producing music in a cramped Kowloon flat, using the city's late-night rhythms as his only audience. His sound fuses the glossy nostalgia of retro synthwave with textures pulled from Hong Kong itself — distant ferry horns, market chatter, and rain against corrugated awnings, all woven beneath pulsing arpeggios and driving basslines. Tracks like 'Halfway Home', 'Back When', and 'Body Talk' have earned him a quiet but devoted following among fans of cinematic, atmospheric electronic music, drawing comparisons to genre stalwarts while carving out a distinctly East-meets-neon identity of his own. Costaine rarely performs live, preferring to let his music unfold as a soundtrack to imagined night drives along the harbor — but when he does play, it's often from a rooftop, synthesizers glowing against the skyline he calls home. 'If You Only Knew' Step back into the neon glow of the 1980s with “If You Only Knew”, an upbeat retro synthwave journey filled with shimmering analog synths, driving basslines, punchy drum machines and that unmistakable feeling of a summer night that never seemed to end. Bright, melodic and effortlessly nostalgic, the track captures the excitement of youth, late-night drives, neon lights and memories that somehow feel closer than yesterday. Press play, turn up the volume, and let Costaine take you back when everything felt possible. #Synthwave #80sNostalgia #RetroMusic
