DS13 is an excellent drummer and plays in his school big band. He wants to play in a rock band but "doesn't know anyone". Now, when I was at school, a thousand years ago, you just put a note on the student notice board in the music department, or asked kids who you saw dragging instruments about, or just heard someone singing to themselves and approached them. I'd probably been in half a dozen different "bands" by his age. Apparently "no-one does things like that" and it would be "rude" to approach someone who you didn't already know, especially if, shock horror, they were in a different year.
I've pointed out that he's now at secondary school and it's up to him to take the initiative on these kind of things, not parents and teachers but he still seems to be of the mindset that there are grown-ups who organise all this kind of stuff for you.
How did other parents of burgeoning musicians encourage them to self-start? I know in the classical world its more usual for parents and music teachers to be the ones organising ensembles etc, but in the rock and roll world it kind of goes against the whole spirit of the thing!
