This is the OST of One Piece Film Z, released on 15 December 2012.
Music have been composed by TANAKA Kôhei (Angelic Layer, Gunbuster, One piece TV, Sakura Taisen, ESPer Mami), HAMAGUCHI Shiro (n°4-7-8-9-12-14-16-18-22-23-25-26-26) and NAKATA Yasutaka (n°1).
On the songs side, we find: - a insert song sung by the seiyuu of Aokiji Kuzan, KOYASU Takehito. The symphonic composition of TANAKA Kôhei is really beautiful, maybe one of the best song of One Piece. Note lyrics has been written by the script supervisor of this movie, SUZUKI Osamu.
- and two ending themes performed by Avril LAVIGNE, "How you remind me" (n°29) & "Bad reputation" (n°30).
Basically, this OST is reserved only for One Piece's fan or for those which have seen the movie. For me, except for some tracks, BGM are unfortunately less memorable than the TV serie.
