Preservation Hall Jazz Band Spearheads Benefit Single

New Orleans' Preservation Hall Jazz Band is no stranger to charity partnerships. Earlier this year, they teamed up with artists such as Ani Difranco, Del McCoury, Paolo Nutini and Jim James to release a two-disc collection of classic jazz songs under the header Preservation: An Album To Benefit Preservation Hall and The Preservation Hall Music Outreach Program.

The band spent the spring on the road with My Morning Jacket. And if you arrived late to the May 1st show at Merriweather Post Pavilion, you missed a master class in New Orleans jazz.

Now Preservation Hall has its sights set on a new cause: addressing the environmental disaster afflicting the Gulf Coast. As The Gulf Aid Allstars, they've enlisted the help of Trombone Shorty, Tim Robbins, Lenny Kravitz and Mos Def for an update on "It Ain't My Fault."  Amid the vibrant, swinging jazz passages, Mos Def delivers a variations on what "BP" might stand for.

The track was released on iTunes this week with proceeds being distributed by the Gulf Relief Foundation.
