Bob Dylan has posted another previously unreleased track from The Cutting Edge 1965-1966: The Bootleg Series Vol. 12.

Due out Nov. 6, the latest installment in Dylan's lengthy Bootleg Series focuses on a particularly prolific period in his career, delving into the sessions that produced his classic records Bringing It All Back Home, Highway 61 Revisited and Blonde on Blonde. The latest pre-release leak from the set focuses on one of the best-known tracks from the first album in that trilogy, the Bringing It All Back Home cut "Subterranean Homesick Blues."

As Consequence of Sound notes, this version — which you can hear above — blends together different takes on the song, offering listeners an opportunity to experience its evolution from acoustic demo to full-band track; hardcore Dylan fans will also note a series of differences between what's heard here and what ended up on the final version.

Dylan has posted a new video for the song, which you can watch above, that also incorporates previously unreleased material — in this case, heretofore unused footage filmed by D. A. Pennebaker for the original (and often imitated) promotional clip.

The alternate "Subterranean Homesick Blues" arrives on the heels of two other early peeks at The Cutting Edge, starting with the posting of "Sitting on a Barbed Wire Fence" two weeks ago and continuing with the more recent release of a previously unreleased version of "Can You Please Crawl Out Your Window."

As previously reported, The Cutting Edge is being issued in a variety of configurations, including a budget-conscious double-disc version, an expanded six-disc version and a comprehensive limited-edition 18-disc collector’s box. According to a Dylan source quoted by Rolling Stone, there's still plenty left in the vaults for subsequent Bootleg Series volumes — including a potential set of "pre-album stuff where Bob is just singing songs in Greenwich Village coffeehouses" as well as in-depth looks back at "Blood on the Tracks, Infidels, Oh Mercy and the gospel albums."
