1. Immortal Technique
2. Eminem
3. Nas
4. Plan B
5. Hopsin
There are so many others though, I like Odd Future (more Earl Sweatshirt but Hodgy and Domo are good too), Childish Gambino, Watch The Throne, Mac Miller, UK rappers like Prof Green, Wretch 32, Sway, Devlin, Kano etc.
Hopsin is a good artist he got the new song ill mind of hopsin #5 out and Mac miller is good aswell but you all should look up this really good artist Atmosphere-Trying to find a balance
