It’s the summer of 1970, and the Grateful Dead, The Band, Janis Joplin, Buddy Guy, and others are ridin’ that train across Canada, jamming their way from concert to concert in a nonstop party full of sensational performances. This “rock-doc holy grail” (Village Voice), which became an instant classic when it was released in 2003, features the greatest Janis Joplin performance ever recorded: two drop-dead, electrifying numbers that left audiences shaking their heads in astonishment. “Festival Express should rightfully take its place in rock history as one of the great performance films of all time,” says the Hollywood Reporter.
