This is a project that has been years in the making, and the final track has finally been wrapped. One truly dedicated Donkey Kong Country fan has been going through the entire soundtrack to the game and restoring each track to its studio quality. This was made possible by locating the sounds from the original workstation keyboards and drum machines, applying them to the original compositions, and removing the compression that was unavoidable on the SNES.
While YouTube still adds in a level of compression, what you're hearing here is much closer to what the original composers put together before they brought the songs down to the SNES. The end result definitely retains the feel of the SNES tracks, but with much higher fidelity.
The above track is just the first tune in the soundtrack. Click here to enjoy the full playlist! Thanks to Jonathan for the heads up!
