Elton John, The Who, Jimmy Buffett, Tony Bennett and Lady Gaga to perform at 2015 Jazz Fest

Elton John, The Who, Tony Bennett and Lady Gaga are scheduled to headline this year's New Orleans Jazz and Heritage Festival.

The festival annually draws hundreds of thousands of music fans to New Orleans for two weekends of jazz, blues, Cajun, zydeco and gospel. Most of the lineup is from Louisiana but it's accented with national acts. This year they will also include No Doubt, Keith Urban, Pitbull, John Legend, Ed Sheeran and Chicago.

Local favorites returning this year include New Orleans queen of soul Irma Thomas, Troy "Trombone Shorty" Andrews, singer-pianist Allen Toussaint and The Meters.

There will also be a tribute to rock 'n' roll Hall of Famer Fats Domino.

The festival will run April 24, 25 and 26, and April 30, May 1, 2 and 3. Tickets go on sale through Ticketmaster starting at 10 a.m. Tuesday.

In all, hundreds of acts will perform on more than a dozen stages at the Fair Grounds Race Course. Food and craft booths will be set up among the stages with traditional Louisiana fare such as gumbo, po-boys, jambalaya, crawfish etouffee and alligator sausage.

But the highlight is the music.
