In 1970 I saw Led Zeppelin there. They were great but the sound was somewhat “remote” (I did not have a great seat). In 1975 I saw “The Stones” there. They sounded good in the same arena. Then I realized they had the best sound equipment and the best sound people running them. So it is not always the size of the arena that determines how good the sound is going to be. It is more than that.
