Who gives a damn shit how where when why it was filmed. It exceeds any filmed concert up till then including Monterey pop and Woodstock. Even the earlier versions commercially sold on vinyl, or cassettes were different. I don’t care if it was filmed from cameras hanging out of there ass. It is awesome and the energy was unequal. Only three others come close. Kiss Alive (the first) Framtom Comes Alive and Skynerds one more for the road. There’s several but as far as rock blues psychedelic and stage control. I’m a Led head till the end. Thank you.
