Last month, it was announced that the 15th volume of Bob Dylan's bootleg series was announced.

The release will focus on a session from 1969 where Cash and Dylan spent two days in a Nashville studio jamming and singing eachother's songs. It'll feature outtakes from the 1967 John Wesley Harding sessions and the Nashville Skyline sessions that have never been bootlegged.

Today an unheard demo titled "Wanted Man" has been released. As Pitchfork notes, the track was originally written by Dylan for Cash to sing.

The bootleg sessions are highly sought after, and will feature 47 unheard tracks. Only a few of the takes have leaked in the past, but this will be the first time the sessions for Nashville Skyline, John Wesley Harding, and his sessions with Johnny Cash will be available in full.

A source close to Bob Dylan told Rolling Stone, "Besides the very early folk years, you don’t have Bob playing with a lot of other major stars up until this point in his career. Here you have him doing duets with Johnny Cash, Carl Perkins, and Earl Scruggs. It’s a really deep dive into some of the music that he loves and just a really cool package. I think people will come away from it enchanted by the breadth of his catalog."

"Wanted Man" is out now. Bob Dylan (Featuring Johnny Cash) — Travelin’ Thru, 1967–1969: The Bootleg Series Vol. 15 will be released 1 November via Columbia Records / Legacy Recordings, and is available to pre-order now.
