On Cendre, Christian Fennesz plants a forest for composer Ryuichi Sakamoto to get lost in. The Austrian fuzz abstractionist sets down his usual bed of serene guitar and digital noise that fogs the air while Sakamoto's piano melodies delicately fall into the ether. Ambient artists may have trod similar ground in the past, but there are still sublime moments. Fennesz draws most of the attention-his vivid timbres prick the skin like dusk sunlight on "Kokoro," and his guitar drones walk skyward on "Amorph." The only weakness is that Sakamoto's loud piano sometimes intrudes on Fennesz's soft ambient backgrounds. Still, Cendre is a fine soundtrack for watching the day end.
