I only had a chance to glance at it yesterday morning, but read the whole thing trying to unwind after a particularly rowdy wedding reception gig last night. (yeah - on a *Tuesday* night... who the heck planned that?!)
Anyway, I guess that's the most comprehensive article I've ever seen on the Wall of Sound. Fascinating, the back story... Thanks for posting Rusty!
As an aside, I had this buddy in high school, (we're actually still buds, just separated by a continent anymore) that famously huge sound stytem was all he thought or talked about leading up to the Dead tour that year (either Summer of '86 or '87) by which time I guess they wouldn't have been using it anymore. Tried his best to get me to go with him, but I didn't heed his accolades about this *amazing* Phil Lesh guy on bass. I'd like to have that one back.
