Other post-WWII Chicago bluesmen are better known, but the work of Elmore James holds up as well as any of theirs. If he never had the technical accomplishment of, say, Earl Hooker, he did have as much depth of emotional expression as Muddy Waters; just listen to the sweetness of "I Need You" or the pain of "It Hurts Me, Too." The Sky Is Crying: The History of Elmore James contains some of the most important work of a man who still reigns as the king of slide guitar; anyone who wears a bottleneck today owes a debt to James. Highlights include Robert Johnson's "Dust My Broom," which James made his signature tune, as well as the title track, which contains some of the sweetest licks in blues history. --Genevieve Williams
