alt Hacker NewsThat's not what the Wikipedia page says and it's not even sourced.
Production of the movie started right at the end of the lengthy recording sessions (reminder that Discovery started being a thing late into the Homework recording sessions, with Short Circuit & One More Time being early productions) but it's rather uncertain how this process started. The one thing that I'm 100% sure of, is that the entire production was funded by DP themselves, and they are probably the only owners of the golden master of the movie. (Hence their media team's fault about the absolutely crappy 4K remaster and noise around it, that led to that awful Epic collaboration).
Singles were released at rather odd intervals for Discovery in particular (according to Bangalter, all songs were conceived as potential singles) and music videos were released after the singles.
EDIT : To be honest, it's a bit tricky to be 100% sure about the actual process, with most of the claims being unsourced random internet shenanigans, and the tendency of some people (hi Pedro) to rewrite history whenever they wish.
I can’t speak for where you’re based, but in the UK the music videos for the singles were aired when the singles were charting and before the albums commercial release.
There is no way the anime and the movie wasn’t part of the original albums concept and neither the part you quoted nor the link I shared disagrees with that point.
I agree the album is an album of singles. But that was never in dispute.
I also deliberately avoided discussing the themes of the songs and plot of the movie but musicians are frequently reinventing meanings to songs. And if the history of operatic movies has anything to go by, it’s that musicians seldom have a coherent plot for these things (regardless of whether you’re Philip Glass or The Who) so it’s usually better to just enjoy the randomness of these movies for what it is. But that doesn’t mean that the anime wasn’t still part of the original album concept.
