The beautiful track “Kalte Luft,”German for “cold air,”comes from Kobe, Japan”“based Hirotaka Shirotsubaki. It’s a nearly eight-minute drone with a loose, organic tonality. By “organic”is here meant that there are enough layered elements that the texture is ever changing, the effort throughout evident in a micro-scale level of detail, all tiny, incremental shifts and alterations. At a more macro level, the piece is a sequence of tufts and and flares, billowy, morphing waves and sharp, piercing grace notes. It’s a highlight of the album *Étude 1*, available for free download from Bandcamp, which is a four-song split between Shirotsubaki and his fellow Japanese electronic musician Sleepland:
