When he was in middle school, Yamakawa's father died of throat cancer; as his condition worsened, he eventually lost his voice, the primary faculty with which his work as a news anchor was based.
Yamakawa cites his father's loss of voice to his own interest in Tuvan khoomei throat singing as it is generated by vibrations deep within the body.
Using Tuvan throat-singing techniques, Yamakawa manipulates sound by integrating throat and lung produced utterances with a learned control of his heart beat.
The performance included charts, data on Japanese life-expectation, and internal scans of the human body to visualize heartbeats into years, minutes and seconds.

As each geiger counter clicks from detecting radioactive isotopes that are emitted from the soil, the tactile transducers cause a vibration in the guitar strings to play a dissonant soundscape.
The content of the spoken word portions of the piece referred to the movement, commerce and other impacts of humans on the natural environs of Tokyo Bay.
