Đêm Cửu Long Không Ngủ
Retro Hong Kong city-pop vibe with shimmering synths, spring reverb guitar licks, and tight mid-tempo drums; male vocals, slightly smoky tone. Verses stay intimate and hushed over muted bass, chorus blooms with bright pads and octave harmonies, subtle sax fills answering vocal lines. Final chorus lifts with key change, tambourine, and airy ad-libs for a cinematic, rain-drenched ending.
