Morphosis' epic remix is more spaced and spooked than the original — the dread in check — but still body-rocking and stepping, 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 — an eerie, garbled sublimity, like a kind of black-magic plainsong. Magnificent work by Rabih Beaini.
