On August 13, 1975, The Grateful Dead played a show at the ridiculously small and distinctively decorous Great American Music Hall (GAMH) in San Francisco. This was one of only four concerts the band played that year, all of them in San Francisco. The setlist was mostly comprised of songs from the album Blues for Allah, which had not yet been released. Many Deadheads revere the GAMH performance as an all-time favorite.
