At night, during the Persian new year celebrations in Spring, the inhabitants of Los Angeles become the hosts to memories of Tehran. They no longer speak English, but a Persian idiom. Neon lights fill the streets with psychedelic colors. During this interval, like the old roman technics of the memory palace which used space visualisation to memorize information, the material space of the ephemeral and mutant territory of Los Angeles streets are used to host the memory of Tehran one last time before disappearing.
