In March 1970, Bob Dylan recorded some of the most spare, exquisite and personal music of his career – mostly old folk tunes and country-comfort covers – with David Bromberg and Al Kooper. Dylan didn't release the tapes in that form. He sent them to Nashville, where, with overdubs, they became the foundation for the ornate, divisive Self Portrait. The original sessions comprise the heart of this vital, revealing collection, part of Dylan's Bootleg Series. Far from being lost and uncertain at the end of the Sixties, Dylan was at his most exploratory, testing directions on the way to his next, essential LPs, including New Morning and Blood on the Tracks. That extraordinary decade starts here.
