Here’s something of a surprise treat for techno fans: a first 12″ in 20 years from legendary Dutch acid techno combo Random XS. The two tracks featured were originally recorded, but never released, in the ’90s, and have been brought back to life by Random XS in collaboration with other producers. “Errant”, which was co-produced by fellow Djax-Up Beats graduate Binaural, is a spacey affair, with undulating acid lines working in tandem with woozy chords, bubbling electronic melodies and clattering analogue percussion. Lost Trax lends a hand on flipside cut “Truant”, which explores deeper techno territory via relentless rhythms, percussive builds, darkly ambient chords and deep space electronics.
