A new planet has been discovered in our solar system! Its mass is ten times larger than the Earth's. Its diameter is two to four times larger. Astronomers call it "Planet 9". As its discovery still has some mystery and no visual data, imaginations grow about this puzzling matter. While there is no visual shape in the sound, the performers offer many stories and scenes in the music. My intention is for you to create your own Planet 9. I greatly appreciate Viva! Saxophone Quartet for premiering and recording this work.
