Lenny Kravitz and Mos Def are set to take part in a benefit gig to support those affected by the recent oil spill in the Gulf of Mexico.
The huge slick, triggered by an explosion in an oil pipe, is threatening to cause widespread environmental damage along the US coast.
The benefit gig at the Mardi Gras World River City in New Orleans on Sunday (May 16) will also feature Ani DiFranco and Allen Toussain.
Proceeds for the concert will help support locals whose livelihoods are dependent within the area, reports the BBC.
The US government has said responsibility for the slick rests with the pipe's owner, BP.
