Bob Dylan, "Fragments — Time Out of Mind Sessions (1996-1997): The Bootleg Series Vol. 17" (Legacy)
"Time Out of Mind" was a pivotal Dylan album because it was 1) his best collection of original material in two decades, 2) his last project for which he used a producer (he's helmed all his subsequent discs), and 3) another instance, like 1975's "Blood on the Tracks," in which he recorded two different versions of the same album.
The first sessions were essentially demos cut by four musicians at producer Daniel Lanois' El Teatro Studios in Oxnard, California. That's curious; Dylan was never known for making demos. The final version was recorded at Miami's Criteria Studios, with an all-star cast and Lanois processing Dylan's vocals in a way that had never been done before. The sessions were tense. Hence, "Fragments" features alternative versions of songs as well as outtakes.
