The New Orleans Jazz and Heritage Festival announced its much-anticipated cubes. The easy-to-read, cube-format schedule contains performance times and stages for the seven days of Jazz Fest.

See the cubes list here .

Jazz Fest runs April 24-26 and April 30-May 3 at the Fair Grounds Race Course. The cubes were unveiled at Fair Grounds during the festival’s traditional “month-out” press party.

This year’s top draws include Ed Sheeran, the British pop star who recently scored a No. 2 song at Top 40 radio with his multiplatinum hit “Thinking Out Loud.” Sheeran’s million-selling album, “x,” recently won best British album” at the BRIT Awards and was nominated for album of year at the 57th Grammy Awards. Sheeran performs Saturday, May 2, on the Gentilly Stage.

The cross-generational, starry duo of Lady Gaga and Tony Bennett will perform Sunday, April 26, on the Gentilly Stage.

As in previous recent years, 2015 Jazz Fest headliners include multiple classic rock stars. The Who performs Saturday, April 25, on the Acura Stage. Elton John appears Saturday, May 2, on the Acura Stage. The Who’s and John’s British peer, Steve Winwood, performs Sunday, May 3, on the Gentilly Stage, just before Dr. John’s Louis Armstrong tribute there. And American classic-rock band Chicago takes the Gentilly Stage on Friday, May 1.

Jazz Fest shows its usual eclecticism, however, with younger and older acts than the classic-rock stars. Jerry Lee Lewis, the 79-year-old rock ’n’ roll pioneer from Ferriday who inspired ’60s rock stars, performs Saturday, May 2.

Stars appearing at the festival this year who emerged in 1990s include Southern California pop-rock-ska band No Doubt, featuring frontwoman and “The Voice” coach and judge Gwen Stefani. No Doubt performs Friday, May 1. Thursday, April 20, Georgia’s Widespread Panic likely will draw thousands, making that day of Jazz Fest unofficial jam band day.

Sunday, May 3, will be a great day for New Orleans music fans. New Orleans’ classic funk band The Meters will play a reunion show on the Acura Stage. The Gentilly Stage lineup includes a reunion by The Radiators and appearances by Deacon John and the aforementioned Dr. John.

Festival officials also presented the 2015 Jazz Fest poster Tuesday, featuring the late Big Chief Bo Dollis, the Mardi Gras Indians chief who died Jan. 20 at 71. Local artist Randy “Frenchy” Frechette created the vibrant portrait of a smiling Dollis in radiantly full costume.

Dollis, an especially fitting choice for the Jazz Fest poster, and the Wild Magnolias Indians tribe he led, pioneered the melding of Mardi Indians chant with New Orleans funk and rhythm-and-blues.
