Yeah. There are a lot of old schoolers that even don't EQ anything.
I guess I'm an oldschooler then, haha
I find that the better the equipment I use and the more talented the artist, the less EQing I do. I'm recording a band right now where I'm using 6 mics on their Marshall/Orange stack. No EQ. The band before these guys were rocking a Vox AC30 for all their clean channel stuff. Again, no EQ at all.
So many of us studio nerds get wrapped up in GASing about this, or figuring out some VST setting for that, to the point where we forget our primary task - capturing sound. If it sucks at the source, it's not going to get much better with EQ, compression, reverb, pre-amps, etc.
But back to orchestration. I'd LOVE to record something like that. Again, if you have a talented group of professional musicians, you'd be surprised at how easy this might be to mix. Acoustic instruments, like French horns, violins, cellos, timpani, etc. are so incredibly dynamic and don't require anything but the instrument and the musician to be heard. Therefore, all of your tone comes from the player, so it's just up to mic placement and mixing.
