Northern Electronics label founder Anthony Linell, venturing from Abdulla Rashim moniker, now follows non-alias debut, Consolidate (a tape steeped in dungeon synth) with Emerald Fluorescents, a 12-inch steered back to spiny, unmerciful techno. Atmospheric yet martial, a spray of dazzling tracer rounds, Emerald Fluorescents is relentless, continuously advancing, though not without precise adjustments undertaken with neurosurgical focus. “Fractal Visions,” one of the album’s longer tracks, implies its overarching beat through modulating directional patter. Is this for physical movement, or a contemplative vehicle? The meaning may be that the difference is meaningless. Over five minutes in, neurons rightly synched, whistling keys redirect the pulse to a more ambient terrain. So I guess just absorb.
