Throughout his career, Johnny Cash sang about the downtrodden, giving a voice to the voiceless. But his 1964 concept album, "Bitter Tears: Ballads of the American Indian," started a new conversation about social awareness.
The collection of songs written by Cash and Peter La Farge provided strong commentary about the U.S. government's mistreatment of American Indians. Cash's record label tried talking him out of releasing the album, fearing it would alienate his country music fan base, but his regard for speaking out against injustice was more important.
Kris Kristofferson, Emmylou Harris, Steve Earle, The Milk Carton Kids and others transform Cash's political statement into a rootsy collection in the new album, "Look Again to the Wind: Johnny Cash's Bitter Tears Revisited."
