With Tsugunai's impending release, many Yasunori Mitsuda (best known for his musical work in Xenogears and the Chrono series) fans were wondering how they could get their hands on the OST. The simple answer is: they can't. At least, not yet.
As Mitsuda has been unable to convince Sony to release the game under any of their labels (since Tsugunai does not fall under the Digicube contract most of his Square-contracted works have in the past), he is currently planning on releasing it under his own label. This will be the first CD published by his company, Procyon-Studio. In addition to the announcement, Mitsuda has also decided to give the first copy to the lucky 500,000th visitor to his site.
No release date has been set as of yet, but those interested should keep their eye out at their import store of choice.
