Years before Osu! Tatakae! Ouendan/Elite Beat Agents would make the concept popular, Mad Maestro! focused on a small group of young musicians devoted to helping the helpless (an unlucky-in-love lothario, an audience-free circus ringmaster, etc ) through the power of music. And this was powerful music ... when performed well, it could literally bring the world to life, making trees sprout and buildings bounce up and down on their foundations. When performed badly, it could be disastrous, infusing the environment with a gloomy black haze that seemed destined to engulf the entire world in sadness.
