The Pimps.
 

Anyone else heard of 'em? They had a song on the MI:2 soundtrack years back, and then released "To A Cool Person, Stay That Way" in '00. Sort of a blend of 70s cop-show funk and metal, and it actually sounds really good.

I'd advise you to at least check 'em out. Any of their songs work, but start with:

Sumpin'
Muthafuggaz
Job Opportunities
Rocket Science
Grandma's Christmas Shirt

And besides, any band from the Midwest (edit: Illinois) that calls themselves The Pimps is instantly cool.
