This 25-minute stage poem is told by a cloud in first person, drifting through the shared skies of humankind. It reflects on how our once-boundless atmosphere has been shaped by natural disasters, industrial fires, wars, and capitalism. Each vapor trace carries fragments of memory, linking individual lives to history’s vast machinery. Blending meteorological simulation (indoor clouds), projection, lighting, sound, and performance, the piece turns the cloud into a forgetful historian—inscribing and losing chronicles. Wind, as sound, becomes eraser and agitator; light is the scribe, glitching and overwriting memory. Humans are the cloud’s shadow and voice, emerging where vapor meets light. From the primordial vapor at the birth of atmosphere, to ancient seers divining omens in the clouds, to the sun-swallow smoke of volcanic eruptions and industrial revolutions, and to the mushroom clouds of war. Wherever we are, our lungs are linked to this atmosphere through each breath. Every gust of wind, every wisp of cloud carries humanity’s unending desires, shaping the heat and cold of this world.
