Jun Senoue on Sonic Generations Original Soundtrack:
Seaside Hill, the first stage of Sonic Heroes, which became the first cross-platform title, and the next Ocean Palace were called as sea level altogether in the development team. The former is my composition and the latter is Naofumi Hataya’s, both of which were what I completed arranging, and that was the reason of showing the sense of unity as sea level through the arrangement. When I saw the Seaside Hill of the modern version in this game for the first time, I felt like the essence of Ocean Palace was also large, so I thought of deciding something that continued both compositions. On the other hand, for the classic version, Richard Jacques produced the backing track and I completed it by inserting the melody.
Seaside Hill is, from the start, a composition that I completed under the force as I was happy joining the flow from the phrase I played for the first time with a certain old guitar (1966’s guitar called Fender Duo Sonic2, which is older than me) when I obtained it, but the version of this work is my favorite to the extent that I can even think as if it has finally become a complete system with the modern version of this time.
