is this the greatest live band of all time?

Guitarsam, if you say it is the greatest live band recording of all time, so it is. Your perception of music is the most important; however, I pray that you're not addressing that question to me because none of the above even come remotely close to my perception of  the best.

There are many great concerts mentioned and good choices. I saw the Beatles at Shea in 65. Couldn't hear them very well with all of the screaming girls, but as an 11 year old kid it was one of the most amazing experiences of my life. I was sitting in the fourth box behind home plate with my friend, his parents and his older sister. Could not have been in better seats, except for the three boxes in front of us. It was crazy. Teenage girls were climbing over me to go on to the field. the police were carrying girls two at a time, one under each arm to remove them from the field. 

Best live concert I ever attended was Hendrix.
