The duad of Welsh Huw Roberts and Norwegian Otto A. Totland, Nest present 20 minutes of pellucid textures and crystal-clear geometries that do not risk being confused with some dopey New Age byproduct. Four tracks outlined by somewhat protective rarefied ambiances, natural-sounding sketches in which piano, brass and woodwinds throw drops of melody that survive for fractions of seconds before disappearing. “The Dying Roar” begins with glorious droning inaction, subsequently flowing into more conspicuous suggestions; but it is the whole 10-inch that deserves a thumb-up, if only for the decency transpiring from every move. The fact that this inhuman evaluator spun this one several consecutive times might imply that he’s getting old. Indeed he is, yet this remains a satisfactory release in its genre.
