On 'Extropy Ground Zero', Kazuyuki Kishino displays an intriguing approach towards the genre of experimental noise. Deviating from his usual genre style, he unleashes two tracks full of percussive blast-beats. The juxtaposition of electronic percussive noise tempo against layers of interweaving swooshes and electronic bleeps provides a captivating ambience of sound, which reflect K.K. Null's unique creative process in noise experimentation.
