In the summer of 1970, several of the era's biggest rock stars, including Janis Joplin, Grateful Dead, The Band, The Flying Burrito Brothers, and Buddy Guy, took to the rails for Festival Express. The show was a multi-artist, multi-city concert tour that captured the spirit and imagination of a generation. The entire experience was filmed both off-stage and on, but the extensive footage of the events remained locked away for decades, only recently having been restored.
