King of the Delta Blues Singers

It's packages like this that turn ordinary music lovers into cynics: First, Legacy bundled mythic bluesman Robert Johnson's entire recorded output into the 1990 two-disc collection The Complete Recordings, and since then the label has unbundled the limited trove for different single volumes — one for the Martin Scorsese Blues project, now two patterned after the original LP releases. Each of these gets a "bonus" track previously available only on the Complete set — here, it's the second take of "Ramblin' on My Mind," which is a mighty morsel, not a meal. As there's no sonic upgrade or vault gem, stay away from this, and seek out The Complete Recordings instead.
