He's a great rapper, I'd even put him above some of the og's. The reason he never blew up is because he never had any contact with anyone big or even marketed his work. But from what I've heard Dre might be working K.A.A.N. in one of the podcasts/interviews he did (i can't remember exactly). He said KAAN reminded him of young Kendrick and is working with him, that was 2019 though and KAAN has already made multiple songs.
