Only three days after debuting the a-side of his first official single in two years, Kode9 has uploaded the b-side for public consumption. Opening with Nintendo charms, “Kan” quickly devolves into a barebones audial assault that will test even the largest sound systems. Most Kode9 tracks aren’t “bangers” in the traditional (knock you off your feet) sense, because there’s something almost uncanny about the way he mangles dubstep, garage, grime, etc. into his ultra-specific blueprint. “Xingfu Lu”/”Kan” is out next Monday (4/29) on Hyperdub.
