With nearly 70 minutes of music, this is a great album, based on Sonic CD and Sonic Spinball. It was produced by Spencer Nilsen. As you can see from the track listing, it has good future, bad future and present time tunes from the Sonic CD time-travel theme.
The front cover has a rarely seen image of Sonic, classicly styled and somewhat abstracted for a more artsy speed look.
This was actually given away when you pre-ordered Sonic 3! What a deal, with all these songs and exclusive art it really is a prize.
