Dutch hiphop isn't really like the albums you mentioned. Most of the beats are a lot rawer, most of the energy seems to be focused on the raps. I mean, Madvillainy is brilliant, so don't expect that level of innovation.
Some names you might want to check out are Extince, Osdorp Posse and Opgezwolle. I'm partial to DAC (De Amersfoortse Cooperatie) myself, but only because they're from my hometown, and I know half of the members. [img]/images/graemlins/smile.gif[/img]
You can probably find most of these guys on [censored] somewhere, but you can listen to nonstop nederhop at
http://www.nederhop.nl as well.
