Jun Senoue on Sonic Generations Original Soundtrack:
Mushroom Hill
The stage of Blue Adventure is composed of Act1 in which we decided to revive the original including the map structure as well, and Act2 that we arranged in such a way that we could utilize the boost, so there are also many parts applied to those for the separation of composition. Mushroom Hill, which was the first stage of Sonic & Knuckles, is a melody of mysterious feeling beyond description and it matched the unique visual of the stage, but for Act2 of this game, we tried to change to a funkier direction.
