NEW ORLEANS, LA — Fats Domino, the amiable rock 'n' roll pioneer whose steady, pounding piano and easy baritone helped change popular music while honoring the traditions of the Crescent City, has died. He was 89.

Mark Bone, chief investigator with the Jefferson Parish, Louisiana, coroner's office, said Domino died of natural causes at 3:30 a.m. Tuesday. In appearance, he was no Elvis Presley. He stood 5-feet-5 and weighed more than 200 pounds, with a wide, boyish smile and a haircut as flat as an album cover. But Domino sold more than 110 million records, with hits including "Blueberry Hill," ''Ain't It a Shame" — in which he sang the lyrics as "ain't that a shame" — and other standards of rock 'n' roll.

His dynamic performance style and warm vocals drew crowds for five decades. One of his show-stopping stunts was playing the piano while standing, throwing his body against it with the beat of the music and bumping the grand piano across the stage. Domino's 1956 version of "Blueberry Hill" was selected for the Library of Congress' National Recording Registry of historic sound recordings worthy of preservation. The preservation board noted that Domino insisted on performing the song despite his producer's doubts, adding that Domino's "New Orleans roots are evident in the Creole inflected cadences that add richness and depth to the performance."

Domino became a global star but stayed true to his hometown, where his fate was initially unknown after Hurricane Katrina struck in August 2005. It turned out that he and his family were rescued by boat from his home, where he lost three pianos and dozens of gold and platinum records, along with other memorabilia.

Many wondered if he would ever return to the stage. Scheduled to perform at the New Orleans Jazz and Heritage Festival in 2006, he simply tipped his hat to thousands of cheering fans.

But in May 2007, he was back, performing at Tipitina's music club in New Orleans. Fans cheered — and some cried — as Domino played "I'm Walkin'," ''Ain't It a Shame," ''Shake, Rattle and Roll," ''Blueberry Hill" and a host of other hits. That performance was a highlight during several rough years. After losing their home and almost all their belongings to the floods, his wife of more than 50 years, Rosemary, died in April 2008.
