When I interviewed for the position at this startup, one of the guys informed me that, if I didn't know already, the music industry is very old school. For example, he said, none of the industry attorneys will use the track changes feature to redline agreements. They mark them up by hand and have them emailed to you as a PDF. This seemed amazing to me, but believable. To be fair, I know older attorneys in the technology sector who still do that.
Sure enough, my experience has been of emailed PDFs with semi-legible question marks and brackets in the margins. Still, I didn't entirely understood what old school really meant, until I got an email from an industry attorney in LA. It was about a paragraph long, acknowledging receipt of our change requests (a proper redline).
At the bottom of the email below his name, it said: "Dictated but not read."
