Query: Great Blues Collection

This album, an overview of Johnny's work on Alligator, is a tremendous statement of Blues-Rock. Johnny's previous work on Columbia was Rock, with a Blues bent, but this is pure Blues.The song "Third Degree" is worth the price of admission, alone. Play it next to Eric Clapton's verion of the same song, and you'll see what I mean.
