Rocked by the deaths of his longtime collaborator The Spaceape and Hyperdub artist DJ Rashad, Kode9 turned to contemplate the void. Despite his preoccupations with absence—The Spaceape himself reappears, as ominous as ever, on the ambient sketch "Third Ear Transmission"—Nothing brims with life, from the tumbling footwork rhythms of "Zero Work" and "Vacuum Packed" to the intricate, minimalist grime of "Wu Wei." As always, the Scottish producer's palette is unusually vivid, full of prickly hi-hats and flickering loops; "Respirator," with its heaving breaths and racing pulse, is like sonic CPR.
