Producer Koji Nakumara operates in many forms, but what unites the various electronic styles that enter the producer’s orbit is the feeling that they are turning into a puddle right in front of you. Nakamura’s latest number, “Marumari,” moves at a brisk pace courtesy of soft but ever-present percussion and sparkly synth lines. Yet for as energetic as it gets, it also blurs together the further it goes along. That makes for a nice contrast as the song goes on, and keeps “Marumari” interesting for the whole run. “Sex,” meanwhile, unfolds much slower. It is sparse, with minimal beats and just some light vocals floating around. But even with this spartan collection, Nakamura makes them all come together just right, and boil together into something interesting. Listen to that one below.
