My childhood was steeped in folk music, and much like those at Newport who were horrified when Bob Dylan plugged in, my parents wouldn't let this group anywhere near their record collection. Consequently, I only knew a few songs like “Whole Lotta Love” or “Stairway to Heaven” before watching this documentary. It begins by introducing each member of the band, and it uses an interview with the deceased John Bonham in a touching way as all four recount their individual musical influences prior to forming the group and creating music history. A great deal of archival research went into the film, resulting in a remarkable collection of material—not just from those who influenced them but also some of their early performances. There's a particularly entertaining sequence at London’s Roundhouse theatre where, already having achieved success in America, they perform for a puzzled group of Londoners – some with their hands covering their ears! I didn’t connect with all of their music, and as one journalist mentioned in the film, they can occasionally be a bit self-indulgent. But so what? That familiar saying about best serving others by first taking care of yourself comes to mind. If you can't enjoy making music your own way, you can't expect listeners to enjoy it—and that pursuit of a musical style that connects with an audience is clearly important to these musicians. It’s interesting to see that even after five decades, they still seem to respect one another and fondly recall not only their touring and recording days but also show a tender fondness for their departed drummer, whose comments evoke genuine emotion from Plant, Page, and Jones. The film contains very few interruptions; instead, it concentrates on the band’s own thoughtful commentary as well as ample footage of live performances up to the release of “Led Zeppelin II,” where their story rather abruptly ends. These are three intelligent and captivating men who have clearly experienced life's highs and lows fully and intensely and emerged remarkably balanced from a music industry that they refused to let define them. Their music might not appeal to everyone, but as an account of an era, a band, and a genre-defying style of rock, this is an easy film to watch for two hours.
