Musical. The way it is written, it's pretty much ready to be staged.
This.
Not to rain on parades (Broadway reference?), but I don't think it's anywhere near ready for the stage. All of the stuff that isn't in the song text -- the information from the descriptions on the website -- would have to be added as new lyrics or spoken dialogue for the story to make sense. As an album, where we can read along with the lyric sheet and other supplemental information, take multiple listens, discuss and analyze, it's great. But as a stage musical, the audience has to understand everything on the first listen, and that just isn't happening here.
Furthermore, what happens during the instrumental sections? Dance? Action? Scene changes? Sure, for some of them, but other sections would have to be shortened or rearranged or cut altogether. A *lot* of additional writing and rewriting is needed before this is stage-ready. How does the narrator function? The ensemble? All of this needs to be figured out. Not to mention reorchestrations, key changes based on singers who aren't JLB doing every part, plot points that need to be rearranged to suit costume and set changes...
I mean, it's certainly written using the blueprint of a stage musical, especially a sung-through rock opera. But to actually take the stage... that would definitely require months, if not years of work!
Sorry if I'm going off on this a little much... musicals are my thing.
Carry on.
