PRAGUE — Prague’s most rocking new fest, Moffom (Music on Film/Film on Music) unspools its fourth edition today at the city’s most ornate prewar movie palace, the Kino Lucerna.

Hip crowds figure to fill the Wenceslas Square edifice for concerts, panels and more than 60 docus and features, plus some 25 music videos. Rockumentary helmer Don Letts presents his BBC-produced pic “George Clinton: Tales of Dr. Funkenstein,” and Ben Barenholtz, an early distributor of U.S. independent talents of the ’70s and ’80s, preems his helming debut, the jazz docu “Music Inn.”

The fest’s country focus highlights Russian cinema, with a preview of Michael Apted’s “The Long Way Home,” a Glasnost-era portrait of rock rebel Boris Grebenshikov of the underground band Aquarium.

Ten competish pics include Nigeria’s musical social history “Suffering and Smiling” by Dan Ollman and Spain’s “Nomads TX,” which follows two virtuosi of the Basque instrument txalaparta.

Fest wraps Monday with a kudos presentation.
