Considering the level of reverence Bert Jansch elicits from Boomer Rock icons like Neil Young and Jimmy Page, it’s surprising to learn that the 67-year-old Scottish guitarist/singer/songwriter is their contemporary rather than their elder. But by 1965, when Young, Page (and Donovan, another Jansch acolyte) were still searching for their musical direction, Jansch had already made one of his greatest albums, as important as any to ever come out of the British Folk revival.   

Director Davis Guggenheim ('An Inconvenient Truth') brings together Rock music legends Jimmy Page and U2's The Edge with The White Stripes' Jack White for an eventful behind-the-scenes look at how these great musicians communicate with each other and create music. Impromptu jam sessions and individual strolls down memory lane reveal the guitarists' childlike passion for their chosen instrument and their sources of inspiration from divergent musical influences.
