A more important reason is that the bands will intuitively trust someone they think is a peer, and who speaks fondly of the same formative rock and roll experiences.
If the label presents them with a contract that the band don't want to sign, all the label has to do is wait. There are a hundred other bands willing to sign the exact same contract, so the label is in a position of strength.
We have no general conceptual thrust for the band, other than trying to make music that keeps our interest. When things are novel, they are probably things we have discovered by accident or investigation rather than by design.
There is a lot of use of ProTools in professional studios, but this is mostly for the special effects it allows, not for sound quality. These special effects soon fall out of fashion, and I don't think this trend will define studios permanently.
The woman I am currently crazy about was a vegetarian for a year until I started dating her. As is the case with most vegetarians, she had never eaten properly prepared meat, only commercially packaged or otherwise abused flesh.
Many rock musicians are excellent cooks, I've found, and those that are prefer to eat their own cooking in the studio. I encourage this behavior as I also enjoy the benefits of fresh food.
Make no mistake about it: once a band has signed a letter of intent, they will either eventually sign a contract that suits the label or they will be destroyed.
Know what you're trying to do before you do it. Turning knobs at random isn't enlightening any more than throwing paint at a wall blindfolded will let you paint a nice picture.
In 1980, I moved to Chicago, and I recorded demo tapes for my friends' bands, and in 1981, the first Big Black record - the first thing I did that was an actual record.
I'm busy doing my job, and being a loudmouth doesn't appeal to me as much as when I was younger and had the youthful delusion that I was smarter than everybody else.
