Bob Dylan has released the previously unheard track "Sitting On a Barbed Wire Fence," which appears on his upcoming collection The Cutting Edge 1965-1966: The Bootleg Series Vol. 12.

The song was recorded on June 15, 1965 during the sessions for Highway 61 Revisited and features Al Kooper on organ and Mike Bloomfield on lead guitar.

The Cutting Edge 1965-1966: The Bootleg Series Vol. 12, which will be released on November 6, chronicles the 14-month period in which Dylan released Bringing it All Back Home, Highway 61 Revisited and Blonde on Blonde.

The collection will be released as a two-CD or three-LP set, a six-CD box and a 18-CD, 379-track collection that contains "every single note" that Dylan recorded in a studio in those two years, as well as a 180-page book, nine mono 7" singles, a strip of film cells from the Don't Look Back documentary, and a leopard-skin print spindle.
