Punk has been denying the rumors of its demise since at least 1981, when The Exploited released the seminal Punk’s Not Dead and launched a million backpatches. Since then, the genre, while not dying exactly, has seen its fair share of respirators and bedsores, with aging godfathers gamely trotting themselves out for creaky reunion-tour cash, Johnny Rotten and Henry Rollins turning into reality-TV stars, and snot-nosed ignoramuses forming bands “influenced” by Blink-182. On the 30th anniversary of the year that punk broke, filmmaker Susan Dyner’s exhaustive documentary takes a razorblade to that fat and bloated subject, ripping it up and starting again by interviewing nearly evry band that ever mattered (including members of The Damned, Ramones, Subhumans, Black Flag, Minor Threat, and Dead Kennedys) and combining them with vintage and modern performances for a probing, philosophical look at the punk movement and its sociopolitical context. Far from just another self-congraulatory tribute, Punk’s Not Dead puts the music through the prism of history, giving it life one more time.

Documentarian D.A. Pennebaker has long maintained a lucrative sideline career as a director of music films, hitting big with Monterey Pop, the Bob Dylan travelogue Don’t Look Back, and the O Brother, Where Art Thou?-related concert video Down From The Mountain.In 1973,Pennebaker was invited to shoot the “final” concerts of David Bowie performing under his glam-spaceman guise. The resulting Ziggy Stardust And The Spiders From Mars has rarely been screened since its initial midnight-movie showings, but a revamped soundtrack and renewed interest in the entrepreneurial Bowie has sparked a reissue of the film that best captures (in dimly lit fashion) the showmanship and decadence of glam rock.
