Casey MacGill performs music that swings. Nat "King" Cole Trio meets the Mills Brothers. Fats Waller meets Fats Domino. Slim Galliard meets Fred Astaire. It is American music of many decades and no decade in particular, all happening at the same time and woven into a seamless, beautiful whole. At the core of Casey MacGill’s sound are his band's sometimes sweet, sometimes rough-hewn, three-part harmony vocals and a piano-ukulele-bass-and-drums rhythm section that swings in a variety of textures.
