Yeah great stuff Jolagh! I've been slowly working my way into the realm. Took a huge hiatus a few years ago, still haven't come back to it. A friend and I were talking about starting a splits only label then, I love that idea. Way too much on the plate now, maybe one day.
I don't know a ton about it, but your point sounds right on target. Something Massy said a lot was really about just being open and finding what works. Don't just stick with a formula.
Albini's ideas on an engineer's goal should be the gold standard IMO. He talks about how his #1 goal is to just record what the artist does as close to how they hear it in their head. Then you can move on from there.
Personally I like that idea a lot. I've always wondered if there were any non "basement" studios that excel in the genre.
Btw, I was pissed about our big studio experience...not a bad rate, but just aa poopy experience. I was optimistic too, Filter, Ted Nugent, Soundgarden, and and others recorded there. But they didn't give a poopie about us and just wanted to loop us in to 10+ days of recording and mix work. None of us were gonna let that fly with how they operated.
Got to see the master tapes for Fred Bear and Hey man nice shot though, if that's worth anything.
