I dunno, man... a rebellion against giant corporations in the future?

Then again, I read comic books, so *shrug*

>'ziggy stardust'

maybe, but the concept is presented rather vaguely throughout, correct? Also, I tend to think of it as a perhaps better version of the same cautionary fable as Tommy - the rise and fall, dangers of excess, etc.

huh, musical concepts is a better idea than a lame story, which most concept albums seem to entail. But it's a slightly different beast.

>Nine Inch Nails - Year Zero (dystopian future)

>Nine Inch Nails - The Downward Spiral
>(http://www.4degreez.com/nailz/ninterpretations/downspiral.html)

I don't have time to read that second one, but is that a case of superimposing an interpretation onto a completed work? I know that part of the fun of art is varied interpretations by listener, but to me a concept album is in large part defined by the artist's intent.

>J Dilla - Donuts (the concept is subtle--you have to pay
>attention to the song titles and sample sources and contrast
>it all with his life--but present; happy birthday and rest in
>peace)

never considered the idea, probably couldn't ID the samples well enough to connect the dots.
