This is one of Chris Cornell’s last recordings called “You Never Knew My Mind” with all lyrics by Johnny Cash.
Here’s the full story posted by the Johnny Cash page:
In 1996, Johnny Cash recorded a cover of Soundgarden’s hit “Rusty Cage,” written by frontman Chris Cornell, on his Grammy-winning album ‘Unchained.’ Twenty years later, Cornell wrote the next chapter in this unique musical relationship by setting a newly discovered poem of Cash’s to music, to create the stunning all-new song “You Never Knew My Mind.” It was recorded at the historic Cash Cabin Studio in Hendersonville, TN, and marks one of Cornell’s final solo recordings.
The song is featured on ‘Johnny Cash: Forever Words,’ out April 6 on Legacy Recordings, a division of Sony Music Entertainment. The album is comprised of Cash’s unknown poetry, lyrics, and letters, now set to music by an all-star array of contemporary artists. Along with Cornell, the album features new songs by Ruston Kelly & Kacey Musgraves, Rosanne Cash, Alison Krauss & Union Station, Kris Kristofferson & Willie Nelson, Brad Paisley, John Mellencamp, Carlene Carter, Elvis Costello, The Jayhawks and more.
