The title references the Japanese white-toothed shrew (Crocidura dsinezumi) - an early indication of animal themes that would become prominent following Akita's veganism adoption in 2003. The shrew exists in perpetual urgency, eating constantly or dying - a quality resonating with Merzbow's relentless intensity. These tiny creatures live at the edge of metabolic possibility, their hearts beating impossibly fast.

This prescient animal reference - predating Akita's formal commitment to animal rights by over a decade - suggests that ecological and zoological concerns were present in his work from relatively early stages. The shrew's frantic energy mirrors the recordings' restless movement, sounds scurrying through the mix like small creatures through underbrush.
