So wide is the appeal for Jingle Bell Rocks! that the documentary can be embraced by Christmas-music fanatics and foes alike. From Thanksgiving to New Year’s, its subject is virtually inescapable to the ears of America’s shoppers, drivers and diners, yet what tickles the tympanic membrane of one tortures another. While lending credence to both groups, the film unmistakably stands on the side of letting such sounds snow.

Its audience surrogate is also its director and producer, Mitchell Kezin. To say he’s (chest)nuts over holiday harmonies is an understatement; the man collects seasonal slabs of vinyl and polycarbonate plastic like a skid-row prostitute does STDs. In this, his first feature, he travels cross-country to talk with fellow collectors, as well as creators of timeless classics and outright obscurities.

Among them are cult filmmaker John Waters, who shared his love for oddball, tinsel-strewn tunes with the masses via the 2004 compilation album A John Waters Christmas; Run-D.M.C.’s Joseph Simmons, who recounts how he wrote the 1987 charity track “Christmas in Hollis” over a spliff and eggs; and The Flaming Lips ringleader Wayne Coyne, whose mother’s unreliable TV memories led the alt-rock iconoclast to birth the 2008 sci-fi film Christmas on Mars (certainly the only soundtrack album to contain such Yuletide gems as “The Gleaming Armament of Marching Genitalia” and “In Excelsior Vaginalistic”).

Bringing a side dish of gravitas to the party is Kezin’s own narrative about how his Christmas-music obsession is fueled by hole-in-his-heart memories of hearing Nat King Cole’s “The Little Boy That Santa Claus Forgot” as a child pining for his absentee father. His bittersweet recollections culminate in a moment that gives Rocks! a climax that can be forgiven for feeling a little forced, because Kezin has accumulated so much goodwill in the interim. With impressive animated sequences and, ironically, no soundtrack disc of its own, it’s a doc as accomplished as it is infectious. —Rod Lott

Adjust Your Tracking is not the only VHS-fetish documentary in the neighborhood. The same year’s Rewind This! beat it to the punch — barely — but whereas that one chronicled the history of the home-video format from birth to death, this one dispenses with such lessons in about 12 minutes in order to devote itself to the almighty collector. Rewind covered that ground, too — just not at this length.

Here, although with overlap, the focus is on VHS enthusiasts — not necessarily among the millions who made every weekend night a Blockbuster night in the video-store era, but those who today pursue those clamshell-encases plastic rectangles with the fervor of a dog to strips of bacon. Yes, I’m talking about the collector, who obsessively scours flea markets, thrift shops and garage sales for tapes. Judging by those interviewed by co-directors Dan M. Kinem and Levi Peretic, the titles hardly matter; in many cases, the movies won’t ever be watched much less freed of factory wrapping. The subjects’ fervor appears to be more about the sheer act of acquiring the objects than viewing them.

They’re the guys who bid mercilessly on eBay for the shot at proudly proclaiming they own Chester Turner’s Tales from the Quadead Zone — a legitimately terrible shot-on-video effort, but hey, it’s pink-steak rare! Some of the guys consider themselves historians of sorts or cultural archeologists who “save” such relics from landfills because no one else will, yet I’d hardly compare their mission — as one interviewee does — to that of our World War I and II soldiers.

And therein lies my only problem with the never-dull Tracking: the perpetuation — if not glorification — of a VHS-collector stereotype. Almost always male, the collector is arrogant, bearded, overweight, immature, single, poor, likely OCD and possibly removed from reality. Whether or not that’s a legitimate sketch, it’s the one we’re given. —Rod Lott
