Xiaomi will never forget the magical sounds she heard one hot summer night when the power went out in her family's apartment building. It happened towards the end of the day while her parents were peacefully preparing dinner. As her father lit a candle, he suggested they take out their musical instruments and descend to the park to perform for their neighbors. He played the erhu and her mother the accordion while she danced. The songs made their way into each home and soon, everyone joined the concert, laughing and singing under the moonlight, celebrating the music that had brought them together. The picture book is accompanied with recordings of the narrated story and the theme song.
