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

Hey, OP, how about some follow up?  Always appropriate.  Personally, it always feels manipulative when someone posts something of at least some controversy or possible misunderstanding and then disappears,  

Btw, re  **** I’m not so sure about that. Phill looks pretty damn old. ****

He should, he’s dead.

I’ll abstain from personal judgment, but I think that another way of saying what I think you are trying to say is “orchestral music is to chamber music what Phil Spector (and his *wall of sound*) is to (most) Rock & Roll”.  There is some truth to that, but so what? 

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.
