Like, wow man, that IS a wall of sound!

I attended about 10 shows with this system and don't think I've heard it's better yet. A few shows latter on they experimented with surround in a delayed system covering the hall.Anyone hear this?

Airtaxi, I see where John Curl was a consultant on this system. I was in an audio shop in Berkeley about a month ago and this unassuming, but very friendly guy is in the store and we begin to chat. He obviously knows a GREAT DEAL about the amp I had in there and several other topics, so I ask him if he works there. He says no but he's worked on a lot of equipment. After about 10 more minutes, says he has to run and gets in his car and drives off. One of the guys from the shop comes out from the back and says, "Oh, I see you met John Curl". THEN he tells me!

I'm not sure how many times I heard the Dead with that sound system (but am pretty sure the Jersey City concert was one of them). I saw a lot of Dead shows in the early to mid 70's. The Wall was fantastic for instruments, but I didn't really like the way it handled vocals. IMO the out of phase mike setup took the bottom out of the singing, and made voices sound tinny at times.
