The acknowledged kingpin of the Louisiana school of blues, Lightnin' Slim built his style on his grainy but expressive vocals and rudimentary guitar work, with usually nothing more than a harmonica and a drummer in support. It was down-home country blues edged two steps further into the mainstream, first by virtue of his electric guitar, and second by the sound of the local Crowley, LA musicians who backed him being bathed in simmering, pulsating tape echo. As the first great star of producer J.D. Miller's blues talent stable, Lightnin' Slim had a successful formula that scored regional hits on the Nashville-based Excello label for over a decade, with one of them, "Rooster Blues," making the national R&B charts in 1959. Combining the country ambience of a Lightnin' Hopkins with the plodding insistence of a Muddy Waters, Lightnin' Slim's music belonged uniquely to him, the perfect blues raconteur, even when he was reshaping others' material to his dark, somber style.
