"The Sky Is Crying" is a slow-tempo twelve-bar blues song that has become a blues standard. First recorded by Elmore James, "The Sky Is Crying" reached #15 in the Billboard R&B chart in 1960. Accompanying James (vocal and slide guitar) are his longtime backing band, the Broomdusters: J. T. Brown (saxophone), Johnny Jones (piano), Odie Payne (drums), plus Homesick James (bass).

Elmore James was credited as the sole song writer on his Fire Records single. However, over the years, several names have appeared alongside his on various reissues and covers of the song. In 1991, Elmore James' "The Sky Is Crying" was inducted into the Blues Hall of Fame in the "Classics of Blues Recordings - Single or Album Tracks" category.
