Yasiin Bey, better know by his rap name Mos Def, has been banned from entering the country. Mos Def was supposed to leave his current home in South Africa, so he could come back to the states and perform on tour in Boston but he's not allowed to return.
The tour had to be canceled and the tour promoters Together Boston released the following statement.
"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, including May 15th, Together Boston’s show at The Wilbur Theatre. Individual ticket refunds for this show are available at point of sale."
The strange part about this situation is that he was born in Brooklyn. So the exact reason he cannot come back to the states is unknown
