Retrograde Planet

After the colonization of the nine planets, a great interplanetary war broke out. It lasted for over 2000 years. Finally, the populaces of the nine planets agreed to end the war, and instead to have a battle of the bands to decide once and for all which was the most powerful of the planetary bodies. The winner of the competition, a band from the planet earth named Zazen, is now making a victory tour, in the year 3939, of the nine planets. We join them, live on the planet Mars.
