John Heckle's debut album Second Son was undoubtedly one of 2011's highlights, traversing eclectic terrain, from beatless ambient interludes to raw analogue jams and heaving acid. Mathematics offers a timely reminder of how stunning it was with this twelve inch offering of the four tracks that featured on the CD release but not the double LP edition. The ever lolloping "One Self" demonstrates the Liverpudlian McNulty lookalike at his subaqueous, tape chewed best, whilst the beatless "I & I" oscillates with wildly experimental tones and vague hints of eastern enlightenment. From here, the orchestral touches that grace the deliciously utopian euphoria of "Fly City" provides some welcome respite while the brilliantly named "Analog Bulldog" jackhammers away at your senses with a relentless energy. The four tracks here encapsulate perfectly why Jamal Moss was so keen to release Heckle's long player.
