A documentary exploring a new form of masochistic chorus, where performers push their bodies to the absolute limit using choking techniques while singing. Merging the ecstasy of masochism with the aesthetics of vocal performance, it shatters boundaries. Captured in shocking footage, three women strive for the perfect voice through extreme states of asphyxiation, eye rolling, convulsions, and fainting. [Ando Haruno] possesses modest vocal ability, yet descends into intense states of eye rolling, convulsions, and rigidity, plunging into complete physical collapse. [Shiotsumu] conveys deep devotion to singing even through agony; her repeated fainting and detachment from reality create a jarring image, as if transcending human limits. Here, innovative compression techniques, shocking loss of consciousness, and hauntingly beautiful vocals merge into an otherworldly artistic expression.
