For undetermined legal reasons, Mos Def denied entry into America. 

The rapper Mos Def, now known as Yasiin Bey, has reportedly been denied entry into his native United States ahead of an upcoming tour.

The Together music festival in Boston wrote on its website: "We regret to inform you that due to immigration / legal issues Yasiin Bey is unable to enter back into the United States and his upcoming U.S. tour has been canceled."

The details of the issues are unclear, but Bey no longer lives in the US having moved to South Africa. He recently told Rolling Stone about the move: "I lived in Brooklyn 33 years of my life. I thought I'd be buried in that place. And around seven years ago, I was like, you know, 'I gotta go, I gotta leave.' It's very hard to leave. And I lived in a lot of places. Central America. North America. Europe for a while. And I came to Cape Town in 2009 and it just hit me. I was like, 'Yeah.' I know when a good vibe gets to you. And, you know, I thought about this place every day from when I left.
