Fats Domino is best known for nailing down a laidback R&B groove—think 1956's “Blueberry Hill”—but New Orleans' amiable piano icon stretches out further across his catalog. Observe the hangdog romance of “It Keeps Rainin'” and the surprisingly successful country overtures of “Whiskey Heaven.” Then behold how he turns Beatles outliers like “Lady Madonna” into strutting, swaggering, Southern-fried romps.
