Big Bill Broonzy & Washboard Sam (LP)

Although Chess didn't bother to anthologize these sides into album form until the early '60s, this marvelous collection actually dates from 1953. Broonzy and Sam are both in great form here, sharing the vocals throughout and recalling their earlier days as Bluebird label and session mates. The sound is fleshed out by the addition of guitarist Lee Cooper (who at times almost sounds a bit too modern for the genre being explored here, throwing in what can only be described as Chuck Berry licks) and Big Crawford on upright bass.
