U.S. Blues by the Grateful Dead from their 1974 studio album, The Grateful Dead From The Mars Hotel.
The first part of the video is a short film I found called "200." It was made to be some sort of trippy propaganda in 1975 and was put out by the US Gov't Information Agency for the bicentennial. Vincent Collins did the animations for that video. I put the rest at the end together.
Happy 4th of July, my friends!
