Charles Hamilton!
 

 

this guy is MAD TALENTED, seriously.. both his flow + lyrics are on point. he is obsessed with the color pink & Sonic the Hedgehog, lol.
the only thing that stopped him from blowing up is being literally insane. i think he suffers from Schizophrenia.
still, one of the freshest rappers i've heard! plus he produces most of his own shit and his beats sound awesome.

"Loser" Music Video
"Brooklyn Girls" Music Video
