On May 16, the Psychotronic Film Society’s long-running weekly series of underappreciated and/or rare feature films continues at The Sentient Bean with a somewhat unusual variation on its standard fare. That night, in honor of the impending 77th birthday of the great singer-songwriter, author and artist Bob Dylan, the PFS will exclusively screen a special two-hour collection of live clips of Dylan and his band in concert, none of which have ever been officially commercially released, and most of which have never been seen publicly.

These excellent-quality clips will be sequenced chronologically, and contain material recorded clandestinely from 1991 to 2017 at Bob Dylan shows all over the world. The cumulative effect is that of being an audience member at an imaginary concert featuring songs spanning the Bard’s entire career, often rearranged drastically to conform to the densely layered style of eclectic Americana he introduced on his 1997 Grammy-winning Album of the Year “Time Out of Mind,” and which continues through his latest albums and current tour.

This screening is recommended not only for diehard enthusiasts of his work, but also for those with merely a passing interest in just what makes Dylan such an enigmatic and charismatic figure in the world of popular culture. Immediately prior to the screening, there will be a raffle for a variety of Dylan-related merchandise and rare, unreleased recordings known only to private collectors. Showtime is 8 p.m.
