"Depending on his mood, Fats Waller could be ‘the cheerful little earful’ or ‘the harmful little armful’. Usually, he was both, winning a huge following in the 1930s and ’40s with his high-spirited, satirical takes on run-of-the-mill popular songs. He transformed his material with a sense of humour, ebullient vocal style and the infectious swing enshrined in the name of his jumping sextet: Fats Waller and His Rhythm. But jazz fans and musicians prized Waller's glittering piano style. He was a product of the demanding school of New York stride players, whose formidable technique was matched by competitive zest. They challenged each other wherever there was a piano and Waller often prevailed with his sparkling invention and the dexterity, power and finesse you might expect from a sometime pupil of Leopold Godowsky. Waller’s taste for classical music was as natural to him as his genius for swing."
