Their music can't remotely be described as jazz, but The Black Keys , along with Phoenix and Dave Matthews Band , are among the acts who'll be performing at the 2013 edition of the New Orleans Jazz & Heritage Festival, which takes place over two weekends from April 26 through May 5 in the Big Easy.

Other acts on the bill for the musical extravaganza include Gary Clark Jr. , Band of Horses , Andrew Bird , Mutemath , Better than Ezra and dozens more.  Tickets are on sale now at NoJazzFest.com .
