For 30 years, the Grateful Dead were the most unlikely success story in rock and roll. At the peak of their popularity, they were the highest-grossing concert act in America, but they did it by breaking all the rules.

This monumental documentary will meld a cornucopia of never before seen performance footage, vintage interviews, and other candid moments unearthed from the Grateful Dead's vast vaults along with newly captured conversations with surviving members Mickey Hart, Bill Kreutzmann, Phil Lesh, and Bob Weir, as well as many other characters and pranksters from the Dead universe.
