Shanghai’s underground bass scene has been reshaped in recent years by wider economic and cultural shifts, with familiar venues closing and long-running communities dispersing. Out of that gap comes 19Hz, a new collective formed by DJs and promoters who grew up around Phreaktion’s drum & bass legacy. Rooted in drum & bass, jungle, dubstep, UK garage, and soundsystem culture, the project looks back as much as it looks forward, drawing on shared history while testing new directions. The focus stays on low frequencies, physical dancefloor energy, and rebuilding a sense of community at a time when the scene is still finding its footing again.
