This music is composed-through, as no part should repeat itself. It uses a single sample for five voices on six tracks (one track is an ambient texture), most likely from György Ligeti - to whose music this track may look up in awe.
Made with Caustic / mixdown in Reaper with some fx.
Sample origin: "JR_ligeti.SF2"
