Totsuzen! Neko no Kuni Banipal Witt (partially found soundtrack to anime film; 1995)
Totsuzen! Neko no Banipal Witt (known as Catnapped! in North America) is a 1995 anime film directed by animator Takashi Nakamura (animation director of Akira and director of A Tree of Palme and Fantastic Children) and co-written by Chiaki J. Konaka (of Serial Experiments Lain and Digimon Tamers fame)
While the film has gained some degree of notability following its American release for its bizarre and creative visuals, what's less known is that the film had spawned a handful of merchandise in its native Japan, namely a couple books and a soundtrack CD.
Published by Toshiba EMI on July 19, 1995, around the time of the film's original theatrical release, the soundtrack contains the incidental themes to the movie as well as its end credit's theme song "Yume e No Tobira" as well as another song and a karaoke version of it.
While "Yume e No Tobira" has been posted on YouTube, none of the other tracks on the soundtrack have and the CD is incredibly rare (if copies can be found at all), with most sites no longer selling the CD.
