Howlin Wolf's the Real Folk Blues is by far my favorite. A close second is Muddy Waters sings Bill Broonzy but save your money and find an original as the Speakers Corner isn't very good (I have both). Son House on Columbia 360 label is a must. I second Gelmhirsts' recommendation of the Jimmy Reed lp. A sort of recommendation is a compilation album called Reconsider Me by Elvis. If he had sang like that more often I would have stayed a fan forever!
