Re: Sound Engineering School Advice ???
I have less experience than Bo, but I do have some experience of engineering in a theatre, live bands and recording - both studio and live across different styles.
My advice from a competency point of view is to actually get your son to listen to a lot of different kinds of music. I've met far too many sound engineers whose idea of 'Jazz' and 'Classical' is so far off the mark it's beyond a joke and as a result have no idea how to actually cater to it. Bo's absolutely right about ridiculous hours - his examples are far worse than mine, but you basically have to expect to be on the go all the time and not have any significant support. Technical knowledge is something you have to pick up quickly as well and it helps to keep your finger on the pulse technically and artistically.
The best thing your son can do is to start teaching himself basic principles. It's amazing how much you can learn from simply attending a few local gigs and getting to know a promoter - sometimes you can get chatting to the sound engineer and occasionally (at the local level) they might not mind you giving them a hand with cable runs and other menial things. I would be careful not to step on toes in that instance, but getting to know people can give you a good idea of what is expected of you and in numerous cases you would learn what not to do as well.
If he has any kind of disposable income now, I would suggest that he invest in some basic recording equipment. It can give you a serious headstart if you have an idea of what you're doing before you start a course. I came to University with a three-year headstart on most of the other people and it has served me well. I'm not going into engineering as a profession, but I know enough to be useful and were circumstances better, would specialise in Classical recording.
