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

Symphonic music has a wider tonal pallette than chamber music. Plus greater spatial effects.

Kinda like that but symphonic music came along way before Phil Spector. So it’s more like Phil Spector is like symphonic music got hold of Robert Johnson or Louis Armstrong or Billie Holliday or Bob Dylan. 

Mapman: I’m not so sure about that. Phill looks pretty damn old.
 

I think some miss the point. Phil Spector took the genre R&R and (in his own words) “augmented” the more traditional size of ensemble used in R&R and through the use of larger ensembles and the exploitation of studio techniques created a sound often referred to as a “wall of sound”; same style of music, much larger presentation.  Chamber music is typically Classical music for a small ensemble while, by comparison, Orchestral music is the same genre composed or orchestrated for much larger ensembles.  Clearly an oversimplification and no qualitative judgment suggested, but same idea as Spector’s approach.

In the 1960's Spector was referred to as the Wagner of Pop music. He was great with Girl Groups and other singers/performers, but when he tried to regain relevance in the 70's and beyond, it became anachronistic. The Ramones produced by Phil Spector?!
