Björk sounds great on her new single "Nattura." Thom Yorke (that guy from Radiohead) adds smeary, windy way-ambient backing vocals, but the most prominent ingredient is Lightning Bolt drummer Brian Chippendale's dark, heavily tribal percussion. (He also brought that amazing end-times feel to Volta's "Dull Flame Of Desire.") This new track, written/produced by Björk, and which includes Matthew Herbert on synth/bass and longstanding ally Mark Bell on electronic beats, might bring you back to Post (or maybe Liars on Enjoyed). Whatever the case, it feels different and darker than Volta.
