In JINGLE BELL ROCKS!, director Mitchell Kezin delves into the minds of some of the world’s most legendary Christmas music fanatics and hits the road to hang with his holiday heroes – including hip hop legend Joseph “Rev Run” Simmons of RUN-D.M.C., The Flaming Lips’ frontman Wayne Coyne, filmmaker John Waters, bebopper Bob Dorough, L.A. DJ and musicologist Dr. Demento, and Calypso legend The Mighty Sparrow. In his search for the twelve best, underappreciated Christmas songs ever recorded, Kezin both asks and answers the question, “Why, when Christmas rolls around, are we still stuck cozying up with Bing Crosby under a blanket of snow?”

After being denied a promotion at the university where she teaches, Doctor Lily Penleric, a brilliant musicologist, impulsively visits her sister, who runs a struggling rural school in Appalachia. There she stumbles upon the discovery of her life – a treasure trove of ancient Scots-Irish ballads, songs that have been handed down from generation to generation, preserved intact by the seclusion of the mountains. With the goal of securing her promotion, Lily ventures into the most isolated areas of the mountains to collect the songs and finds herself increasingly enchanted.
