The record will be released on April 6th through Sony's Legacy Recordings. It will also feature Kacey Musgraves, Rosanne Cash, Alison Krauss & Union Station, Kris Kristofferson & Willie Nelson, Brad Paisley, John Mellencamp, Carlene Carter, Elvis Costello, The Jayhawk, Ruston Kelly and of course, the late Chris Cornell.

John Carter Cash, Johnny's son, was a co-producer on the new album and he described it as a 'monstrous amassment' of undiscovered material.
