Yeah yeah, there are demos that aren't. But by and large demos consist of dudes playing shitty blues.
Do people even listen to this music?
I don't know of anyone who listens to or plays generic knock off stevie ray vaughn trash. I don't hear it on any radio stations, or at the gym. Only on demos.
I don't think "hrr hrr, blues lawyers" is a valid explanation. It's not just old guys, it seems to be a pretty broad age demographic. Though a very narrow gender and ethnic demographic...
Why?
If no-one makes this sort of music, and no-one listens to it, why are all demos made of this? Is this what guitarist do when they play guitar? They sit down and play shitty blues, despite playing in bands that don't play that music, and despite not listening to that music?
I don't get it.
Rephrase the question however you want so that we don't land in "I watch demoer X who is not a shitty blues person"
