These days, Mos Def goes by Yasiin Bey. He's also switching it up with a move toward comedy.
The 41-year old made his stand up debut in front of a live audience earlier this week at the Phi Center in Montreal.
Bey kept it topical, with jokes about the Meek-Drake beef, and Kanye West's truncated performance at the Pam-Am Games.
See some clips from the show below. Let us know if you think he has a future as a funnyman.
