XXL's "The Seminar Freestyle" series continues with this next video featuring Blu. The reason why Blu is spittin with his back to the camera, and Cudi had his face covered in his video, is because the viewers were supposed to guess who each person is....right. Sorry we spoiled it. The 10 "mystery" emcees will be featured on the cover of XXL's Jan/Feb issue dubbed Top Of The Class.
