The latest slate of rarified Rocky Mountain nocturnal house moods by sharpening craftsman Andrew Dahabrah distills his production instincts to their starkest, most sensual essence. Tight, tense rhythms intertwine with sinuous bass lines overcast by fluttering software gauze and dizzy sequencer patterns, evoking thin air, cold roads, icy peaks, oxygen deprivation. Since 2013 the FOANS discography has deepened at a steady clip, morphing through pixelated ambience, trip-hop abstraction, and bedroom techno – capped by last year’s Schema cassette for austere Danish electronics imprint Speaker Footage – but Frontier synthesizes the project’s strengths in a uniquely persuasive manner: lush, strung out, blissed out, bleary. Dahabrah paints the picture succinctly: “These tracks were made late at night.” Fluid city hazes in high altitudes by a deepening talent. Mastered by Alex Nagle.
