The opening performance that raises the curtain on Moons is Sak, Mang 02—deathofDavid (sak, the new moon; mang, the full moon), a collaboration between Kim Baul and Kyna. The title's sak (朔) and mang (望) are key concepts running through the moon's orbital cycle. Sak, the new moon, is the phase when the moon lies between the sun and the Earth and vanishes entirely from view—the moment when one cycle ends and a new beginning germinates. Mang, the full moon, is the phase when sun, Earth, and moon align and the moon reveals itself whole—the peak at which it attains maximum visibility and fullness. The two artists capture this ephemerality of the moon as it changes within its relative relationships to the Earth and the sun, and translate it into the form of a fleeting performance in which sound, media, and interaction with the audience erupt.

The moments of solar and lunar eclipse, in particular—appearing unpredictably along the journey between sak and mang—offer a deconstructive experience of the idealized, linear time we have taken for granted. The performance organically links the moon's shadow, produced by the Earth's rotation and revolution, with the shadows of the viewers in the gallery. This visual variation, where celestial change meshes with human movement, stirs the audience's unconscious senses and serves as a metaphor for some critical threshold of the cosmos where moon and Earth, planet and human, order and collision intersect.

The two artists visually dismantle the David—the foundational beauty of Western aesthetics and an idealized body—while aurally juxtaposing raw, noise-based sound, opening an entirely new sensory path for the audience. Their gaze moves beyond the binary system of light and dark, toward the infinite possibilities of the cosmos to which the moon belongs. This performance, which will exist only once and then vanish with the exhibition's opening on July 16, resonates deeply with the curatorial vision of this exhibition, in that it offers the most intuitive proposition of the ontological context of the moon—endlessly generated and extinguished—within the museum as a space that is a metaphor for the cosmos.
