(AllHipHop News) Rapper Mos Def will join a number of top musicians who are rallying to help Louisianas coast with a benefit concert called Gulf Aid. Mos will be joined by artists like Lenny Kravitz, Ani DiFranco, John Legend, Allen Toussaint, Rebirth Brass Band and numerous others.The artists are pitching in to clean up over 4 million gallons of oil that has spilled since an April 20th explosion on the Deepwater Horizon off the coast of Louisiana. Its only fitting that the individuals who are the protectors of our culture, the musicians, come to the aid of those who help supply our culture, the fishermen, Mayor Mitch Landrieu said during a press conference yesterday (May 11th). The event will take place this Sunday (May 18th) at Mardi Gras World River City from 12pm-10pm. Tickets are $50 and proceeds will go to the Gulf Relief Foundation, which will benefit the fishermen and their families in the Gulf.
