A four-CD, 80-song box set that, in line with similar Smithsonian productions, outlines the history of blues spanning over 50 years, with cuts by major performers who represent its stylistic evolution. The set is stuffed with classics by the likes of Muddy Waters, Louis Jordan, T-Bone Walker, Little Walter, Big Mama Thornton, Howlin' Wolf, Elmore James, B.B. King, and Buddy Guy, with plenty of slightly lesser-known artists like Lil' Son Jackson, Billy Branch, Big Maybelle, J.B. Lenoir, Doctor Clayton, and Junior Kimbrough. The selections are a tad conservative (if very good), and it's likely that serious blues fans will have a good share of the tracks in their collections already. The set also concentrates much more heavily on 1940-1970 material (which takes up about 75 percent of the contents) than blues from the 25 years from 1970 onward. If your interest falls somewhere between casual fan and dedicated collector, though, it's a good survey of major blues performers and genres, with an excellent historical overview and notes about each performer in the accompanying 92-page booklet.
