If nothing else, M.I.A. is provocative. The singer, who's new album "Matangi" hits stores on Tuesday, opened a show on Friday with special guest Julian Assange. The Wikileaks founder Skyped into the concert from the Ecuadorian Embassy in London, where he's currently living under diplomatic assylum for publishing troves of secret government files and fleeing charges of sexual assault. 

M.I.A has long made clear her suport of Assange by contributing to his television show and naming one of her mixtapes Vicki Leekx.
