If you like "James Brown is Dead" then I suggest you to check out "James Brown is Still Alive" too. That song is in similar style and like a response to original in lyrics.
Yep, sounds similar to early songs of 2 Unlimited but I would rather say that it is L.A. Style's style because 2 Unlimited came little bit later and slowly turned closer to Eurodance than to classical Techno. But I have to agree that 2 Unlimited was far more popular and known in the dance music scene.
Also I can suggest you to listen to "U96 - Das Boot" - another Techno classic and I think my all time favorite in this genre but you might not like it because "Das Boot" does not feature rap. It is a more of a European style if we compare to L.A. Style which is very close to original American dance music.
