The East German techno wiz kid likes it dark and heavy. After only a handful of 12″ releases, Sebastian Kramer unloads a whopping 60 minutes of mechanical repetition and four-to-the-floor hypnosis on Mark Broom’s Pure Plastic label. Keenly inspired from the Detroit sound, each droning track drives through sparse stringy synth pads and relentlessly heady, borderline tribal-y percussion–ranging from drum-laden walls of bass to loopy, shuffly big-room techno. Even though the three closing bonus tracks (not included on the vinyl version) offer a deeper and more leftfield touch, Principles is merely for the gung-ho techno DJ.
