If Aaron Funk was a politician, his promise of three full-lengths by the year’s end might have been as empty as a lot of our wallets. But as an obsessive producer, Funk came through and marked the conclusion to his triptych with a vitriolic departure from both the funky hypergrooves of his spring release, Higgins, and the spaciously glitched-out summertime collection, 2370894. Here, maturation’s the word, with bowed and pizzicato strings modestly braced in the backseat of well-controlled percussive maneuverings, rich basslines and atmospherics breezing over pin-pricking clicks, a minimal cover of The Misfits’ “She,” and build-ups that break down with such gnashing restlessness that they’ll give you nightmares for a week.
