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

But it does raise the question are Fennel's Marches kind of like Phil Spector got a hold of that guy on the street corner drumming on a plastic bucket?

The Classical forefathers are turning in their graves.

Expand your musical horizon.

I think that's an amusing concept! 😄

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? 

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