The Grateful Dead Movie Soundtrack is a five-CD live album by the rock band the Grateful Dead. It was recorded on October 16–20, 1974, and was released on March 15, 2005. The album was remixed from the original 16-track concert soundboard tapes.

The Wall of Sound was an enormous sound reinforcement system designed in 1973 specifically for the Grateful Dead's live performances. The largest concert sound system built at that time, the Wall of Sound fulfilled lead designer Owsley "Bear" Stanley's desire for a distortion-free sound system that could also serve as its own monitoring system. Due to its size, weight and resulting expense, the full WoS was only used from March to October of 1974.
