Teruhiko Nakagawa on Sonic Rush Original Groove Rush:
It turned out that I, who was engaged in Sonic Advance as one of the creators, am assigned the sound of the remodeled DS. When I thought, What shall I change?, I decided to have it made by teaming up with Naganuma, who is well-known for JSR. This is interesting, I thought. The chemical reaction definitely happens and it happens too much after that, and we only guide it so that it does not overstray from Sonic. However, worries were hardly needed. The reason is that his music is different from outward impression and is actually packed with plenty of poetic sentiment. Also including the 7 remixes written for this CD, please enjoy the full volume of groove to your heart’s content!
