From the release:
The addictive and original Boom Boom Rocket is the first music-rhythm game to appear on Xbox Live Arcade. Players trigger rockets to the beat of the music while traveling through a 3D cityscape. The better the player times the explosions, the more spectacular the fireworks effect. The fireworks are choreographed to 10 original tracks created by Ian Livingstone, who recently scored Batman Returns and Project Gotham Racing 2.
