Just released today. No rating from AMG. Anyone know much about this?

This cd is called The Johnny Winter Sessions by Muddy Waters.

Looks to be taken from Blue Sky label releases Winter produced and played on in the late Seventies. Muddy's in fine form and the backing is sharp. Have to look close to see if there is much if any of the rare live material that comprised a Legacy 2 disc set and a live set that came out in the last couple years
