As the second weekend of NOLA’s beloved Jazz Fest kicks off, GRN has a challenge for you. Watch our video commemorating the 2nd memorial of the BP drilling disaster, shot at and around the 2011 Voodoo Experience, and tell us how many of the artists featured in the video are playing the 2012 Jazz Fest.While we don’t think it’s that hard to pick out the fantastic musicians holding “Restore the Gulf” or “Hold BP Accountable” placards, and compare them to the cubes, you CAN head here if you need some help identifying our friends.Once you’ve got your answer, leave it in the comments, and we’ll let you know if (and what) you’ve won. Aaron Viles is GRN’s Deputy Director. You can follow him on twitter here. You can find him Sunday enjoying Foo Fighters on the Acura Stage (hint, Foo Fighters are not in the video… That’s the Sheepdogs).
