Fans of old-time country-gospel will find treasure for their hearts as well as their ears with the latest in the Johnny Cash Bootleg Series, "Vol. IV: The Soul of Truth."

As the old cliche goes, Cash's distinctive bass-baritone voice would compel even if he were reciting from the phone book, but the country legend, who would have turned 80 on Feb. 26, pours soulful zeal into the 51 hymns and sacred songs on the two-disc set.

Lifetime has tapped Jewel to star in The June Carter Cash Story, a biopic about the late country singer, based on son John Carter Cash's memoir Anchored in Love: An Intimate Portrait of June Carter Cash.

Richard Friedenberg (Lifetime's Of Two Minds) will adapt, with Southland's Allison Anders on board to direct. John Carter Cash, Steven Michaels and Jonathan Koch will executive produce.

Stars paid tribute to Johnny Cash for "We Walk The Line: A Celebration Of The Music Of Johnny Cash," a fundraiser to fight Duchenne muscular dystrophy. Kris Kristofferson, Lucinda Williams, Amy Lee, Shelby Lynne, the Carolina Chocolate Drops, Iron and Wine, Jamey Johnson, Rhett Miller, Brandi Carlile, Shooter Jennings and more took turns on stage running through Cash’s songbook of country classics. With a backing band that included Don Was, Buddy Miller and new Rock and Roll Hall of Fame inductee Ian McLagan, the performers put their own touches on Cash’s hits without reinventing them.

As with previous editions of Sony Legacy’s impressive Johnny Cash Bootleg series, Bootleg Vol. IV: The Soul of Truth is a two-CD set containing a mixture of previously released and unreleased material. The focus this time around is squarely on Cash’s gospel side. The 51 tracks come from the 1970s and ‘80s. New liner notes by the late artist’s son, John Carter Cash, sort out the chronology of the music, putting it into context with the rest of Cash’s output.

At the foundation of Cash’s life and music-making was his spiritual fervor, ingrained in him from an early age. His devotion to gospel music stayed with him throughout his career, from one of his earliest albums (1959’s Hymns with Johnny Cash) through one of his very last (2003’s posthumous My Mother’s Hymn Book). Late in life, The Man in Black even recorded the entire New Testament as a spoken-word multi-CD set. Columbia/Legacy’s fourth installment of Cash’s Bootleg Series is entirely devoted to this aspect of the Cash canon, and as such, The Soul of Truth (88697 98538 2, 2012) may be the most raw, personal entry in the series yet.
