Huey Pierce Smith, known as Huey "Piano" Smith (born January 26, 1934, New Orleans, Louisiana), is an American rhythm-and-blues pianist whose sound was influential in the development of rock and roll.
His piano playing incorporated the boogie styles of Pete Johnson, Meade Lux Lewis, and Albert Ammons, the jazz style of Jelly Roll Morton and the rhythm-and-blues style of Fats Domino. Steve Huey of AllMusic noted that "At the peak of his game, Smith epitomized New Orleans R&B at its most infectious and rollicking, as showcased on his classic signature tune, 'Don't You Just Know It.'"
