Since the Singularity of 2045, human race on Earth has been gradually controlled by a huge AI system. There, people lived peacefully in a smart, stress-free system. The music and culture of the past, which promoted anger and rebellion, or which initiated group dancing, were considered dangerous and eliminated, and people were satisfied with the music and art automatically generated by the AI system. They never questioned when they had lost their artistic creativity and it had become a world where only a meek and obedient people could live.
In 2061, sick of this situation, three young guys from Earth explored to Jupiter, where was used as waste-yard of the earth. Ancient music explorer: RHORDES-073 (Ryota), space-time scientist: PROPHET-006 (Shigeo) and ancient engineer ROLAND-303 (Kashi). They had a passion for discovering the culture, art, music, science and technology of the old Earth. Exploring on Jupiter, they found a vinyl record among the industrial waste. The label of that record was "Interspecies records". They decoded the record on an old TECHNICS-1200. The music played with "Dawn Chorus" of the noisy Jupiter is ancient, forgotten music of the human race. Music for dance = Music for community.
