Don't Forget the Beastie Boys. They have been consistantly amazing for 15 years!!!!! how many other rap groups can you say that about???? (a handful at most) They have done more for rap than a lot of other acts. Man think about it, they helped bring live instrumentation into the rap world!!!!! (of course the Roots were a part of this as well) The Beastie Boys are still one of the Best Rap groups of all times. Stop hating cause they're white!!!!!
