What began as a backyard tribute to Jerry Garcia has become a cornerstone of Northern New England’s music scene. One World, One Jam: 25 Years of Keeping the Jam Alive is the story of Jerry Jam, a grassroots festival founded by Dan Webb to honor the spirit of the Grateful Dead and the enduring legacy of their legendary frontman. From watching old Jerry Garcia tapes in a backyard to hosting full-scale jam bands under the open sky, this film traces the evolution of Jerry Jam through its humble beginnings, changing landscapes, and ever-growing community of Deadheads. Culminating in the historic 25th anniversary celebration, its biggest and most unforgettable year, the documentary is a tribute to the power of music, memory, and the movement that’s kept the Dead alive for a generation.
