The New Orleans Jazz & Heritage Festival is usually an event dominated by rockers and soul artists, but every once in a while, a pop star will make an appearance. This year, two big ones are among the headliners: Christina Aguilera and Robin Thicke.

The New Orleans Jazz & Heritage Festival takes place over two weekends from April 25 through May 4 in the Big Easy, and features dozens of artists.  Robin will perform on Saturday, April 26, about a month after his last scheduled tour date; his headlining tour kicks off in Atlanta on February 21.  As for Christina, she's playing Friday, May 2.  She hasn't announced any other tour dates so far this year, but this date may be an indication that more are coming.

Among the other artists on the bill this year: Eric Clapton, Bruce Springsteen and the E Street Band, Santana, Chaka Khan, and many, many more. Find the complete festival bill and ticket info at
