Polish duo Karol XVII & MB Valence are prolific producers and remixers, but Plastic Age feels like the sound of them hitting their stride. The charge is led by "The Bar Around the Corner," with subtle vintage Rhodes offset by bubbling bass synths and, in the background, an ethereal digital hum. On "Simple Minds," shuddering Moogs, trembling bass and clipped guitars collide, but the release's star turn is "Days Without You." It's a rattling house stomp, blasted with eerie analogue keys and dragged along by classic, Adonis-like synth throbs. Such is its confident strut, you could easily breakdance to it; that it threatens to go completely unhinged at any moment only adds to the drama.
