X.O. is a young up and coming MC hailing from Southern California looking to make a name for himself in the music game. Along with running mate Kidd Upstairs, X.O. is looking to establish Rockstar Muzik outside of California where he’s had a steady buzz since he dropped his first effort, Check Please Vol. 1, followed later by Vol. 2. Check out the video for X’s standout Fire In My Shades after the jump, and look out for the third installment of the Check Please series, as well as a collaboration between X.O. and our homie Rap Muhammad to drop really soon. Enjoy.
