An upcoming tribute to Johnny Cash's Bitter Tears: Ballads of the American Indian, features a host of top names including Emmylou Harris and Kris Kristofferson.

The LP, originally released by Cash 50 years ago, features songs memorializing the maltreatment of the American Indian throughout the nation's history.

Harris features on three tunes ("Apache Tears," "The Talking Leaves," and "Drums"), while Kristofferson features on one tune, "The Ballad of Ira Hayes."

"Prior to Bitter Tears, the conversation about Native American rights had not really been had," producer Joe Henry told Radio.com "and at a very significant moment in his trajectory, Johnny Cash was willing to draw a line and insist that this be considered a human rights issue, alongside the civil rights issue that was coming to fruition in 1964."

Bitter Tears: Ballads of the American Indian hits August 19.
