"Memorial Address" is Hamasaki's first extended play (EP). It is currently her longest EP with eight tracks, tallying up to nearly 40 minutes. For the album, Hamasaki's record label Avex Trax hired several Japanese musicians, such as Tetsuya Yukumi, Bounceback, CMJK, Dai Nagao, among others. Those producers are just some of whom worked with Hamasaki on her fourth studio album, the predecessor "Rainbow" (2002). "Memorial Address" is also Hamasaki's first extended play to be composed, arranged, and produced by Japanese producers and composers. She contributed to the album as the primary and background vocalist, composer, and songwriter to every song. She composed two songs with Nagao; "Hanabi: Episode II" and "Forgiveness".
