On the point of celebrating their 10th anniversary, Mouse On Mars remind us of their legacy of quiet brilliance, which began with the subtly wrought polyrhythms and distressed tones of 1994’s “Frosch” EP. What’s strange about the pristine and media-neglected likes of, say, 1997’s “Schnick-Schnack” is not that it hasn’t dated but that it still bubbles like it’s fresh and steaming in the soundlab, future sounds still awaiting wider development and distribution. As relentlessly inventive as Autechre, yet less daunting.
