The tape from Honjima

In the village of Tomari on the main island of Kagoshima Prefecture, Shotaro Aoyama came across a folk song that was sung by the townspeople during a Bon dance.

Since the singers had disappeared, the cassette tapes owned by the islanders were the only source of sound, and the music was produced based on these tapes.
The songs on the tape were sung by five singers who took turns singing them, and were structured like a long story, with the music evolving from Chapter 1 to Chapter 5 according to the song structure.
The B-side contains an instrumental version of the track.
