Wall Of Sound Live, did you ever go to a Grateful Dead Show?
What did they call their tower of speakers? I once saw the amount of McIntosh Amps they needed for that.
I once saw the Stones, big stadium, I think Shea, anyway, walking in, huge towers of speakers, OH BOY, holy crap, we get in.
Living Color Opens. They sound like crap fried with ....
I realized, they were not letting them use the full sound system.
The Stones hit it, you could feel the entire place shake, not as 'Full' as Grateful Dead, but More Powerful, I think the most powerful I ever experienced (Steel Wheels).
You gotta hear the Kinks at the Beacon. During Lola, every drunken guy gets up, shakes in unison, you can see the balcony above you moving, and there's another one above them moving.
If sober, you start to think about the collapse of that bridge at the Hallmark Building.
