These recordings originate in relation to a live performance in Seoul on February 27, 2026. During the piece, Zhu Wenbo suspended several small cassette players containing tape loops from the ceiling, recording, playing back, and altering tape speed in real time while the machines swayed through the air.

It is not a live document, but consists of the sounds contained within each individual cassette. During its making, the material underwent further improvised real-time speed manipulations, becoming transformed again from the original recordings — if such a thing as an “original recording” can even be said to exist.

More about the performance can be found in Orolo’s essay Things, Non-Things, and Counter-Things: What Zhu Wenbo Tended to That Day, included with the cassette edition and downloadable with the digital release.
