The duo of Jason Kahn and Ilios, Astra create a tissue of compound materials which mostly insist on ear-piercing high frequencies that are differently perceived according to the position in the listening environment. Sixteen untitled tracks, pretty short in terms of duration, aggregate and transform energetic flows and icy winds into apparata for the generation of educated noise in finely tuned feedback processes; these interactions constitute a presence both heard and felt, as testimonied by my ears’ inner ringing during the track pauses. Any further description would be useless: this is a classic case in which individual features play a fundamental role in the intention of appreciating something that could be puzzling – if not annoying – for someone whose will is not so powerful, but represents instead a concrete stimulation for the ones whose inquisitive sense doesn’t stop in front of an apparently impenetrable façade. The hypnotic/looping quality of most of these aural footsteps is a useful booster for more powerful consequences; the immersion in a sonic idiom whose peculiarities reveal an advanced architectural intelligence is greatly enhanced by some dramatic spirals, characterized by incessant transmissions of unknown codes. Everything sounds organized, yet utterly unfamiliar. Surgical beauty of the highest rank.
