If you look at that incredible burst of fantastic characters that emerged in the late 19th century/early 20th century, you can see so many of the fears and hopes of those times embedded in those characters.

The way Fatboy Slim layers motifs is the same as 18th-century baroque counterpoint. You have an idea, then you have an answer to the idea in another voice, then you have a counter idea accompanying the original idea, and you build up your texture like that. I'm really into Kruder and Dorfmeister at the moment, and they do the same thing.
