James Moore recorded as Slim Harpo out of Baton Rouge, Louisiana, becoming swamp blues' most commercially successful voice with a lazy, laid-back drawl and a harmonica sound unlike anyone else's. 'I'm a King Bee' (1957) and 'Baby Scratch My Back' (1966) carried his loose, hypnotic groove onto the pop charts and directly into the record collections of the British blues-rock boom. Few blues singles have been covered as often, or by as wide a range of rock bands, as his.
