Is symphonic music kind of like Phil Spector got hold of chamber music?

...and here I'm pondering, when I read mention of the 'wall of sound', I thought 'Grateful Dead'....

It was fun to get lost in a Spector spectacular, actually.  The combination of the physical and the sound field involved would have a venue full of acid heads have a very Different sort of day...:)

Now I'm going to have to dig out my treasured first pressing of Rheingold-a-go-go: The Ronettes Rock Wagner.

Sure, if you completely ignore the metastructure.
