Berliner Stefan Betke's deceptively simple layering of deep bass, ghostly synth echoes and the crackle of a malfunctioning Waldorf Pole filter fused postmodern digital "glitch" music with analog music tradition, brilliantly channeling the form and texture of Jamaican dub into abstract ambient music. Tracks like "Fremd" and "Tanzen" have the familiar elastic rhythm of reggae, with bits of static and barely audible keyboard bubbles doing the work of drums and guitars, but Pole's reference points are usually more subtle than that.
