Vocaloid-user mus.hiba has been teaming up with a lot of folks recently – first, Bo En and him came together for the cut “Winter Valentine” on the English music maker’s Pale Machine release. And now he’s bringing the syllabic sounds of Sekka Yufu to the late-night sounds of Irish producer Harmful Logic’s chilly “Whispery Voice.” So far in his career, mus.hiba’s use of singing-synthesizer sounds has stood out from most Vocaloid music, more ghostly and experimental than most of the stuff on Nico Nico Douga. Yet the sparse, gloomy atmosphere Harmful Logic conjures up on this track makes Yufu’s digi voice sound deeply creepy, as if she’s peaking out of a corner on a foggy street. Usually, mus.hiba wraps up the vocals in dreamy synth washes, but over Harmful Logic’s more sparse production, they just hover and become something else entirely. This song comes off of Harmful Logic’s lovely new album Lost In The World, which you can get here.
