The Bootleg Series, Vol. 12: 1965–1966, The Cutting Edge

The Bootleg Series Vol. 12: The Cutting Edge 1965–1966 is a set of recordings from 1965 and 1966 by Bob Dylan, released on Legacy Records in November 2015. It is mostly unreleased session demos and outtakes from recording sessions for the albums Bringing It All Back Home, Highway 61 Revisited and Blonde on Blonde. Three different versions of the set were released simultaneously: a two-disc Best of edition in the packaging and format standard to the rest of the series after the first installment; a six-disc box set Deluxe edition similar in packaging to its counterpart from the previous Bootleg set; and a temporarily available 18-disc limited Collector's Edition available exclusively by order from Dylan's official website, which also came with nine mono vinyl singles reproducing singles released around the world by Dylan during this era. The Collector's Edition was unique as it included "...every note recorded during the 1965–1966 sessions, every alternate take and alternate lyric."
