Two young swamp blues worshippers -- Pedro de Dios Barcelo and Carlos Jimena -- perform a chemical experiment by mixing the rusty-water-wheel chant of Hound Dog Taylor, the darkness of Skip James, the hypnotic rhythms of John Lee Hooker and R.L.Burnside, the madness of Screamin' Jay Hawkins, the sweet sound of Tampa Red, the killer slide of Elmore James and the essence of Son House. Phew. This, apparently, is Guadalupe Plata, who are playing SXSW 2010. They took some time out beforehand to talk to Spinner.
