The recordings, which are currently in the hands of collector Jeff Gold, previously belonged to a woman who owned the Greenwich Village building where Dylan had rented a room to use as a studio. It's assumed Dylan simply left the acetates at that location when he moved out of the space.

The material includes alternate mixes, alternate takes and a handful of never-before-released outtakes. Among the latter are electric versions of Johnny Cash's "Ring of Fire" and "Folsom Prison Blues," and a gospel-tinged take of "Tomorrow is a Long Time."
