“Elegance & You,” the new single from the electropop duo of Korine, captures percussive/synth warmth and danceability, while simultaneously venting a sense of hopelessness. That desire for intimate connection, countered by the indefinite sense of isolating despair, really moves you. You can catch the tandem this evening at Kung Fu Necktie, where they are set to support Berdmajik and Future States.
