the way that I get around always having to support crap bands (metal and emo is popular where i am) is I put on a gig myself, scrounge a PA off someone (i got my basssist to help out most sundays doin sound at a local church, so we borrow their PA for free), get a mate who does Art A- Level to design flyers, go into a pub and ask them to let you put it on, put on other bands supporting you, taht aren't neccisarily good but you know will bring a crowd TRY TO MAKE IT FREE ENTRY and there you have it, you're headlining a gig and making a name for yourself as a local promoter.
Don't try to change your local scene, start a new one.
Hope this helps.
