Okay, that's it, that way my review right there in the title.
These three CDs have every important studio recording that Muddy Waters made for Chess - all you need besides this is "Live at Newport", and you're set. Well, that, and maybe the acoustic "Folk Singer" album.
Having said that, this is an expensive set, and in spite of some extra tracks (most of which aren't absolutely necessary), it may be too expensive.
The double-disc "The Anthology: 1947-1972" costs almost twenty bucks less, and serves its purpose almost as well. And you can use the money you save to buy Waters' three Blue Sky-albums :o)
