Query: A great retrospective

This is a great retrospective of B. B. Kings work. From the old favorites to the new classics, this boxed set explores forty years in the work of a blues master. The only down side is the rendition of "Right Place, Wrong Time" with Bonnie Raitt, but there are too many great songs in this set for that one to be anything more than a nuisance. If you want a complete blues set, buy it.
