Ladies and Gentlemen.... The Grateful Dead - Filmore East New York City, April 1971
I am reading a book called "You Can't Always Get What You Want" by Sam Cutler who was the tour manager for the Rolling Stones and the Grateful Dead in the early 70s, so I thought I would have to listen to one of the shows that they did during the timeframe that the book is discussing.
One of the interesting thing that came out of the book is that the Dead did not take to the road because they loved to tour so much but rather because they were almost bankrupt and need to play that many concerts to get out of their financial hole.
