Revealed! - Epic Unused Sonic 3D Knuckles Bonus Stage Music Demo

Never heard demo version of Knuckles Bonus Stage music that was unused in the game Sonic 3D. (A version was later used in Sonic Adventure for the “Pleasure Castle“ stage) This demo track was recorded by SEGA for my approval before it was used to base Sonic 3D’s music on. I’m preserving it here. After the fires last year and new ones nearby recently, I would hate this demo to be lost forever. Track composed by Jun Senoue
