This tribute hones in on Dylan’s less-acclaimed output, including the overtly religious Saved album and dubious long-winded tunes like “Brownsville Girl.” The latter benefits from editing, extra beats and a soulful rendering by comedian Reggie Watts. Craig Finn of The Hold Steady and Glen Hansard from the film Once are two more artists who luxuriate in the potential of this relatively ignored material. Liner notes by Jonathan Lethem depict ’80s Dylan as key to understanding the hardworking “permanent companion” he is today. The 1980s generated some absurdly overdone recordings. A few of these were by Dylan. That’s no reason to dismiss the songs.
