by Bill Dahl Retaining photographer Don Bronstein's cover shot of a disheveled bum lying on the sidewalk (some former Chess artist, perhaps?) Sonny Boy Williamson's original 1959 album made it to digital reissue but has now been supplanted by MCA's exhaustive The Essential Sonny Boy Williamson. Still, for a budget price, there are a dozen unforgettable tracks: "Don't Start Me to Talkin'," and his Checker debut; "All My Love in Vain," "Wake Up Baby," "99," "Cross My Heart," "Let Me Explain," and "The Key (To Your Door)."
