Give this boy any melody, he'll corrupt it and intoxicate it with not-very-noble gases. Give him more or less neat rhythms, and he'll break them down completely. So far, we had known a version of Arca that is sombre, somewhat disturbing in his odd, sharp way of taking on a beat. However, on his new EP, “Stretch 2”, there's a certain brightness, and signs of a different sensibility. We told you about the release last week. Today we bring you “Manners”, a somewhat more IDM kind of song that ends with the tones of a Malian kora.
