Got a distinctive melancholic grungy vocalist and sound that can imagine would be used in a film set in the 90s as a vague callback to them noises without having to maneuver around the clawing music label copyrights.
That "movie" was not even actually a movie. All it was ova specials cut and edited to fit in to a "movie". Which explains certain plot holes in the script, why certain scenes are disjointed, or bare thread excuses how the kids got in America. It's been a long while, so I do not remember a lot.Digimon was still very popular - and to be honest had the much superior anime, except Adventure 02; fuck that one - and its movie, while a little disjointed actually had a pretty banging soundtrack.
