In a 1991 commentary with the game's composer Nobuo Uematsu published in the FFIV Minimum Album Liner Notes, he stated that the unreleased track "The Origin" was the first song he composed for the game, and described the song as setting the tone for the rest of the pieces that came after. He also stated that it was originally intended to be the opening introduction theme, but "Red Wings" was chosen instead.
