For this epic record of absolutely beautiful dub techno, Quadrant stretches the barest essentials for techno to their extreme lengths. In addition to breaking the song down to its most minimal ingredients -- bass beats, a sense of rhythm, and filtered high-end sounds -- Quadrant also keeps the song thumping away for endless loops, only making the slightest changes in song structure. For over a minute, seemingly nothing will have changed: the rhythm will remain constant, the tempo will not change, the looped sounds will seem locked in place, and the filtered high-end sounds will stay linear. Yet when the songs last over 15 minutes each, there doesn't need to be much change. Subtle shifts every few minutes go undetected as the listener remains unconsciously mesmerized by the body-shaking low-end sounds emanating from his or her subwoofer. This is body-engulfing music that is intended to cast a sedate spell over the listener, constructing a lengthy journey into one of Basic Channel's landmark records.
