@lordradish I started a whole thread about "noise" music, and I pretty much am where you are with some of the performers.
There's a difference between doing something deliberately and doing something because you have no idea what you're doing and you figure you can get away with random knob twisting and circuit bending because no one will know the difference. Among the regulars in the scene near me I can usually tell the difference after seeing enough shows and hanging out with some of them.
In the other thread I mention how Herbie Hancock broke rules in the 80s, but as he was an established jazz pianist he knew what the rules were when he was doing it and that made him more effective. I think the same is true for the sort of experimental underground electronic stuff: those who have played instruments in bands before have an idea of how music "works" and can use noise to make something deliberately. Sometimes, there are people who haven't played conventional music but happen to be smart and creative enough to make something interesting from scratch.
Just my opinion, of course.
I also get frustrated when I go to an electronic show and I see people heading for the door, chased out by incoherent noise, when I know a good act is coming up next. Some shows, though, are all about noise and that's what people are there to see.
I call it being musical. You generally learn a lot about being musical after playing any instrument for a while. And you don’t necessarily need great chops to be musical.
