There are several dozen tracks thus far in the “sound diary” credited on SoundCloud to Corruption, who gives as a residence Funabashi, Japan. Many are noisy escapades, tagged simply as “sound diary,” while the one dated “2013.11.19” and given the subtitle “like a moth to a candle” bears a second tag: Nanoloop. That’s the name of a popular piece of electronic music software that originated on the Nintendo Gameboy and has been since ported to iOS and Android. What was, back in 1998, an esoteric dream of handheld music-making has become pop culture, an everyday activity. In Corruption’s hands, Nanoloop makes sequences of shiny chiming jangles that ebb and flow like a low-resolution tide. There’s a glitchy quality to it at times, lending the work a welcome complexity, a dark undercurrent to its slow pace. Corruption does not identify which edition of Nanoloop is employed.
