Aphex Twin‘s wicked grin and yellow-eyed glare beams forth from each of his latest gleeful analog electronic slabs. Like an aural expletive lobbed at all the pointy-shoe ‘80s fetishists and their limp synth pop rehashings, tracks like “Pitcard,” Snivel Chew,” and “Afx Acid 4” contain equal amounts of dissonant audacity and sheer technical genius. AFX‘s ancient machines cough up some fascinating techno ghosts.
