Half of OTR sails emotional waters, tacking between alienation and warmth in the style of some '90s IDM. On "OT_R~cord [4.10]," chords descend calmly over constantly fidgeting drums, the effect is a sense of endless drift. Koza can barely bring himself to end it, opting for an abrupt fade-out after six minutes. The unjustly short "served_on_barm [4/3]" is an even more beautiful take on a similar idea.
The other two tracks are harder to decode. On "ROBOCow.exe," tart chords and a rounded, Lowtec-style bassline spar for attention as shrill synth notes tickle the eardrums. "ZRTP [P-Bass_special]" is drawn from dub techno's primordial ooze, its chords rising to the surface like viscous bubbles. In their withdrawn moods, these tracks reflect the EP's theme: privacy in a hyper-surveilled world. (Some track titles reference encryption methods.) You sometimes wish they'd say more, but withholding is what makes Koza's music so engrossing.
