Ever since jungle emerged in the UK in the early ’90s, the so-called hardcore continuum—the lineage connecting jungle, drum ’n’ bass, UK garage, dubstep, and beyond—has been the source of some of dance music’s most thrilling innovations. Exactingly edited breaks, time-stretched samples, and syncopated beats that divide like beads of mercury are among the hallmarks, and decades down the line, these sounds keep morphing and mutating, providing endless opportunities for further innovation. The forward-thinking tracks you’ll find here are deserving of scientific honors in club R&D: Finely attuned to the physics of sound, they go deep into the very nature of bass. This playlist is updated regularly with brand-new tracks, so if you like something, add it to your library.
