Cameron Crowe, the former Rolling Stone writer who went on to direct one of the best rock n’ roll films of all time, Almost Famous, has been announced as the director of a new documentary about Pearl Jam. Indeed, he’s almost finished it, along with two feature films he has also directed. He explains how he kept up this punishing schedule. “We’d shoot one during the week, and edit another on the weekends,” says Crowe. “It kept it all very exciting.”

He also explained to an interviewer that he was given 18 – 20 hours of the band’s archival footage, which he had to whittle down, as well as also shooting further film over the last 18 months. “It’s the best souvenirs of the past,” Crowe revealed. “Some fabled footage you’ve heard exists but have never seen, and some interviews. So while The Union was, ‘How do we buff up the cinéma vérité?’, Pearl Jam Twenty is, ‘How do we do The Kids Are Alright of Pearl Jam, and sonic blast the best stuff?’ It’s a wider scope.”The film is due out in September.
