Original Sound Version has an interview up with the sound team on Super Mario Galaxy 2:
We’ve been very fortunate to sneak some of Mahito Yokota, Koji Kondo, and Ryo Nagamatsu’s time away from their new projects to talk about their work on Super Mario Galaxy 2, which is surely one of the best soundtracks of the year.
We discuss the influence of Yoshi on the game’s score, each composer’s respective contributions, the retooling of music from the original Super Mario Galaxy, and the return of “Gusty Garden” as an anthem for the series. We also talk about some of our favorite tracks from the game, including “Yoster” and “Square Timber.”
Here’s the trailer for the game:
