jackzebra and Billionhappy team up on 回头 — a brief, collaborative single issued on the jackzebra + Billionhappy imprint that folds brittle IDM percussion into warm downtempo atmospherics. Tape hiss, fractured glitches and sub-bass drones push the track toward ambient intimacy rather than club functionality. Fans of experimental downtempo and IDM will find its restrained, leftfield rhythms rewarding.
