On Under the Sun, abstract techno mastermind Mark Pritchard steps off the dance floor and into a free-floating ambient excursion. In place of the almighty beat are acoustic flourishes, musique concrète-style experiments and synth-driven textures, often assisted with some heavenly voices. “Infrared” is ragged and noisy industrial, whilst “Falling” finds Pritchard noodling up and down the scale with warped organ tones. But the gems here are folk singer Linda Perhacs’ haunting vocals on the lush “You Wash My Soul”, and “Beautiful People”, on which Thom Yorke is equally gentle and soulful over a lo-fi Latin beat.
