That was the idea behind the Wall of Sound. I heard the Dead play in the cavernous horse barn at the Indiana State Fairgrounds where I'd heard other bands echo. The Dead sound was loud, but articulate, and you could have a conversation with the guy next to you anywhere in the room. The Wall of Sound was about even distribution.My neighbor's brother had a band in the 70's and they did their own version of the wall of sound - not nearly as huge as the Grateful Dead, but still pretty massive. It was quite incredible how the sound could be loud and every note intelligible at the same time.
The opening chord from "A Hard Day’s Night" played correctly.
