A pulverising, apocalyptic opening gives way to a menacing bass excursion, expertly putting on the frighteners dubwise, before dissolving ambiguously into the amazing, extended vocal treatment — a thread of eerie, garbled sublimity, like a kind of black-magic plainsong. Morphosis' epic remix is more spaced and spooked — the dread of the original version in check — but still body-rocking and driving out of its silences. B-boy rimshots, a rough snare, a thumping kick-drum and spare bass are layered with emotive synths and brilliant effects, as Shackleton's dream liturgy unfolds in its full, twisted glory. Magnificent work by Rabih Beaini.
