There's a beating heart buried in the wintry landscape of Glider, a warm 4/4 pulse that enervates the album's echoing, looped drones and pulls the listener swiftly through the snow. By pinning barely-there electronic beats to his wisps of guitar melody, the Seattle-based producer turns ambient music into a hybrid strain of breathtakingly intimate, small-scale dance music. There's a separation of elements in The Sight Below's songs thats almost meteorological in nature: Tendrils of treated guitar trail lazy patterns in the sky like the Aurora Borealis ("At First Touch"), flicker in the distance like heat lightning ("Dour"), or expand and contract like time-lapse cloud formations ("Life's Fading Light"); running along beneath, nearly obscured by the airborne phenomena, is an ever-present beat, which ranges from the mud-puddle throb in "Without Motion" to the tiny, insistent high-hats in "A Fractured Smile." The tracks evolve at a deliberated pace, but as the tones overlap and the rhythms build, time oozes to a halt and hangs in blissfully frost-bitten suspended animation. With Glider, The Sight Below has created a work of vertiginous sonic depth and exquisite melancholy: techno music for a dark winters night.
