Illa Ghee is a great artist who may not be underrated but I think he is under appreciated by the masses. He has a flow and voice that stand out and he is very witty with his rhymes. One of those true lyricists that has a huge catalog of music and more to come with the new album coming soon called Suede Cigarettes. From what I understand, this album will be available sometime in April. Check out this new track called Gripped Up.
He also just released an 8 track album with his buddy Sean Price called Metal Detectors that you can purchase on iTunes right now here: https://itunes.apple.com/us/album/metal-detectors/1358512095
