From DCIGN:
Wavemaster, the studio responsible for the diverse soundtrack in Sonic Adventure 2, has opened a special site for the little blue guy. The SA2MUSiC Web Site has the newest information for everything that relates to Sonic Adventure 2’s sound and music. Everything from interviews to release information to general wacky comments by the creators. Too bad everything is in Japanese…
The site has released information about, multi-dimensional, the original sound track for SA2 and detailed track list, comments, and explanations for the SA2 vocal collection. The OST will be released Sept 5th and the vocal collection will be released earlier on Aug 28, these dates are both for Japan of course.
Why does so much of the good stuff have to be in bloody Japanese?
