You can't make Dystopian fiction without actually depicting a bleak future, a world gone mad. But to make Dystopian music, you just have to make music that evokes the dreary mood and technologically advanced texture of a sci-fi movie – or just go ahead and bite the Blade Runner score. Sure, sometimes a Def Jux rapper might nod toward the dark direction society is headed in, but the reason their releases so often get the 'Dystopian' tag is because of the grinding machinery and harsh, metallic gleam of El-P's production. Just as some of the earliest innovators in drum machines and synthesizers were tagged as "industrial music," some of the more recent forward-thinking producers make what you might call post-industrial music.
