It’s like the music never stopped: Amazon’s Grateful Dead documentary Long Strange Trip will be released in theaters on 5/26, the same day Rhino/Grateful Dead Records release the soundtrack. Amir Bar-Lev’s doc starts streaming on Amazon Prime Video on 6/2.

Squabbles about the superiority of the 4/28/71 performance of “St. Stephen” over all other versions will have to be put on hold for the length of the film: Four hours.

Long Strange Trip marks the first time Amazon Original Movies and Amazon Original Series have partnered on an original project to be released in theaters and on Prime.

The film features extensive newly shot interviews with Bob Weir, Phil Lesh, Bill Kreutzmann and Mickey Hart plus footage from a lengthy Jerry Garcia interview shot late in his life. Former Warner Bros. President Joe Smith, biographer Dennis McNally, roadies, wives, Deadheads such as Al Franken and Garcia’s daughter add to the narrative.

The film includes more than 75 Dead performances. The official soundtrack featuring rare and unreleased Grateful Dead recordings will be available on Amazon Music. Hallucinogens sold separately.
