The “Ultrapop” tag Yoshino Yoshikawa has embraced in recent years usually works really well — the music he’s released tends to be quite maximalist, with every available space covered by some sort of cute sound or synth. Yet on “Coldsleep,” his collaboration with Suzushiro, he’s leaving a lot of space available, the song as a whole very open and more of a showcase for the vocals. It’s different, but the same warm, twee feeling that graces the more crowded music he works on is present here, just with more room to sprawl out. Listen above.
