Wow. Have you read the book about that concert? I think it's called "Just Like the Night". And of course Scorcese's Dylan documentary is built around that concert.
I bought the Scorcese DVD when it came out a few years ago and enjoyed it very much. I haven't read the book you mention - I'll try and pick up a cheap copy if I find one.
My recollection of the actual concert was that it was no big deal. At that period of my life I was seeing so much live music that it all became a bit of a blur. I was really surprised when it achieved mystical status later, based mainly I think, on one member of the audience shouting out "Judas". I don't even remember hearing that, BTW. However, the music was so loud and distorted that it was difficult to hear anything!
