From September 1 to September 9, 2023, Li Song, Zhao Cong and Zhu Wenbo went on a South China tour together. They performed 8 shows in four cities, and almost every show was different. In two of these venues, they gave very unique trio performances. This album features these live recordings. At E^dge 一脊 in Wuhan (September 6th) they used the "3 lines" feedback system developed by Zhu Wenbo using transducers, elastic ropes and other objects (foil, paper...). They performed in a small alley in front of E^dge, and the slender and long sound blended with the atmosphere of the late night alley. At Nap Room 午厅 in Guangzhou (September 9th), they used amplified balloons, which was also an "instrument" that Zhao Cong often used during this period. Through various loudspeakers, the soft balloons produced unpredictable explosions. In these two recordings, Li Song also used a laptop with built-in speakers.
