Chris Willman Music WriterBob Dylan’s “Bootleg Series” of archival releases recently passed its 20th anniversary without any set yet dedicated solely to his work in the 1980s. The first half of that decade gets its due, finally, with the upcoming release of a 5-CD set that collects outtakes, alternate versions and live or rehearsal tracks from the eras of his “Infidels,” “Empire Burlesque” and “Shot of Love” albums.
