20 years of brutal, no-holds barred techno. Adam X’s Sonic Groove imprint has rarely wavered in intent or in sound, a compellingly consistent watchword for the sort of electronic music that puts hair on the chest of its male fans and God knows what for its female followers. Dasha Rush’s new EP for the label continues in this vein. It’s a cleaner ride than Obtane’s recent 12-inch, but it’s no less intense, trading dank random industrialism for deep tracks that parcel out their steam pipe explosions carefully.
