The Quadrant EP, originally released in 1993 on Carl Craig's Planet E label, was a one-off project by producer duo Mark Ernestus and Moritz von Oswald, also known from their work as Basic Channel, Maurizio/M-Series, Rhythm & Sound and others. Out of print for nearly half a decade, this reissue features the two main titles that reverberate an early 90s Detroit techno vibe and combine it with an early imprint of Basic Channel's timeless trademark sound aesthetic.
