Lenny Kravitz to headline oil spill benefit gig

Lenny Kravitz is to headline a benefit concert in New Orleans to support relief efforts for those affected by a huge oil spill in the Gulf of Mexico.

Ani DiFranco, Allen Toussain and Mos Def will also take part in the event at the Mardi Gras World River City.

Since 20 April, oil has been escaping at a rate of 210,000 gallons a day after an explosion on a BP-leased rig.

Proceeds from the event will benefit fishermen and their families, whose livelihoods depend on the Gulf, as well as organisations that protect Louisiana's coast.

Ewell Smith, executive director of the Lousiana Seafood Promotion and Marketing Board said the fishermen "appreciated" the effort.

"Thousands of families across South Louisiana will potentially be impacted for years to come and will need all the help they can get to survive," he added.

"Without them, we lose a vital part of our culture and heritage."
