Here are some of my favorites:

Atmosphere
Jedi Mind Tricks
Dizzy Rascal
Classified
Cunninlynguists
Blackalicious
Jurassic 5
Athetlic Mic League
Dilated Peoples
Black Eyed Peas

J-5 definitely, they kick so much ass

I like the black eyed peas. Do they sing that one hit song...I forgot it, its like "with his song...with his voice", something like that.

Both J5 and Black Eyed Peas are starting to get way more exposure in the last 2 years or so. I remember going to a concert where they both played about 5 years ago and nobody had heard of them.
