Last month was the 40th anniversary of a truly legendary Grateful Dead show at Maples Pavilion on the Stanford University campus. Not only did they introduce many tunes to their live repetoire that day, but they also used, for the first time live in concert, a prototype of the Wall of Sound (2). And trashed it from the get go. You don't want to skip this. Playlist with links to full concert audio.
