Plaid’s intricate rhythms and textures are so evocative, it makes sense the UK duo would tackle soundtrack work. Their score to the Japanese film Heaven’s Door is more atmospheric and less hyperkinetic than much of their work; it’s even marginally less electronic, with guitar-like sounds giving shape to lyric pieces like the pensive “Non Hoi” and the flamenco-tinged “Veisalgia.” But the futuristic hyper-jazz of “Takeshita Street” ranks alongside their most electrifying IDM excursions, while “K3” is a masterpiece of electro-acoustic sound design—and pensive scene-setting.
