D.A. Pennebaker, the legendary director and cinematographer best known for his work on Bob Dylan's groundbreaking mid-'60s documentaries and 1968's Monterey Pop concert film, died on August 1st of natural causes at age 94, according to Variety.

Pennebaker was among the first filmmakers to perfect the camera as a “fly-on-the wall” during Dylan's Don't Look Back movie, which Pennebaker directed in 1965 and released in 1967, and 1966's Eat The Document, for which Pennebaker served as cinematographer, but has yet to see an official release.

Among Pennebaker's other notable works over the years included the Sweet Toronto featuring John Lennon & The Plastic Ono Band, Chuck Berry, and Little Richard, among others; 1973's Ziggy Stardust & The Spiders From Mars; 1993's The War Room; and 2002's Only The Strong Survive, among many, many more.

During a recent chat with TheLipTV.com, D.A. Pennebaker talked about his groundbreaking work with Bob Dylan in the 1960's: “We never had a complete song in Don't Look Back, because I didn't want it to be a musical film. And (laughs), when we did the second one (Eat The Document), we thought, 'Well, we'll put whole songs in' — which we did — but what we got was a nicer Dylan (laughs), which surprised everybody. He didn't use words the way you usually use 'em or learn 'em all the time. He caught you listening to the way he used two words, or three words together; he'd mix 'em 'round. And I thought, 'Y'know, this guy is a poet. And he's trying to figure out what a poet is.' He was figuring out how to create himself in some way that he alone was interested in.”
