A remix of the Evil Foundry theme from Sonic and the Secret Rings. While I've barely played the game, I do know this music (from Cobanermani456), and I found an MIDI of it. So, here ya go.
FUN FACT: Sonic and the Secret Rings was originally going to be a port of Sonic '06 for the Wii. Due to the utter failure of the game on the other consoles, they scrapped that idea and started from scratch.
Please contact me if you would like to use this in a project. We can discuss the details.
