Sam Shepherd may have spent the last few years offering up off-kilter, jazz-fired grooves and heady ambient soundscapes, but he still knows how to rock a dancefloor. That much is proved by his first Floating Points single for almost two years. "LesAlpx (Extended)" is his most forthright, club-focused cut in ages - a thrusting chunk of rumbling, peak-time techno built around heavy bass, sweaty drums, twinkling electro piano motifs and raging, foreboding electronics. Shepherd teases in the most melodic, rush-inducing elements, introducing spacey synthesizers and dreamy chords midway through. It's breathtakingly good. Flipside "Coorabell" is similarly potent, with acid style electronics, warm chords and sun-kissed electronics wrapped around swinging, two-step influenced house beats and a weighty, sub-heavy bassline. In a word: essential.
