When in 2004 Ondi Timoner's documentary DIG was presented in Sundance - and then won the Documetary Grand Jury Prize - it became an instant classic! Now two decades later, 'the greatest rock ’n’ roll documentary of all time' - as it was dubbed since by Foo Fighters’ founder  Dave Grohl - gets a 40 minutes extended edition with never-see-before footage as well as a new narration by The Brian Jonestown Massacre’s member Joel Gion.
