Looks like OP is gone, but the topic in this thread is very real. For the past year, my 11 year old has been in a band of 10-12 year olds. They play the same kind of stuff OP's kid does. A couple of points that I wanted to provide my perspective:
One thing I would do, as a parent, is insist on earplugs.
This is the ONLY thing I am a control freak about, and I only have power over my kid. For practices and gigs, my son isn't allowed to plug in unless he has earplugs. Period. I've offered my perspective to the other parents, and we always have extra plugs on hand for them to use if they want. The other kids mostly don't wear them.
Oh, I take that back. The other thing I am a control freak about is tuning up. Again, I only have influence over my kid on this, but it's mandatory. And now I don't even need to tell him these things--the earplugs and tuning are habits now. As far as the music goes, he is totally on his own (but he always asks for tips and feedback). I agree that band parents need to get out of the way and let the kids make music.
First, is this a troll thread? Second, what kind of parent does this crap?
You'd be surprised. We bump into a lot of band parents at shows and they are just as bad as the little leauge stereotypes in some regard. In our situation, I am the only band parent that is a musician. These little guys inspired me to start playing out again, and that has been a real help. When I first felt the impulse to be a control freak, I stopped myself and jumped on Craigslist to find a gig. I lucked out and got in a party/cover band with my first audition. I have plenty of opinions about what my kid's band should be doing, but I mostly keep them to myself. When they are very strongly held opinions, I share them with the band teacher and let him handle it.
In our case, we pay a band teacher who is a full-time gigging musician to run the class. We've had issues with one parent trying to control things (proud to say that has never been me). In particular, one of the parents wants the kids to play tons of live shows when they are not ready. My strategy has been to defer to the band teacher on this.
It's funny--this is obviously a trend with School of Rock and lots of rock band classes popping up. I think it's great. But it does short circuit much of the "garage band" energy the kids have when they are just messing around and jamming.

P.S. Any kid playing in a band should read Victor Wooten's THE MUSIC LESSON. Heck, any person playing in a band should read that!
