Jun Senoue on The Best of Crush 40: Super Sonic Songs:

I Am… All of Me

The time when I thought of the part of the lyrics “Black Hearted Evil or Brave Hearted Hero” and wrote it down on a scrap of notebook paper is the beginning of this song. I tried to hum the lyrics along with the melody somehow and left it in the answering machine, and created it lowering the guitar tuning to C, making it suitable for the song. Shadow’s guitar is called baritone guitar and it is longer than those with ordinary necks, so even if I lower the tuning to that extent, the string tension does not have to become slow. In Shadow the Hedgehog’s music that starts with this song, I heavily used the programming and down tuning with industrial tone in order to realize the keywords such as “dark,” “serious,” “heavy,” and “aggressive,” which were mentioned in the music production of this game. The main character Shadow is different from Sonic and the fact of him riding vehicles that look like motorcycles had also been decided, but I wanted the song to have not only speed but also deep impression, so I attempted to have the song with the tempo composed in two stages like this. It’s a popular song especially in the markets of Europe and America, and a song that I and Johnny like very much, too.
