I’m not sure about the bounty idea, but I’ll tell you what does work if you want your favorite undiscovered band to play a show in your town: offer to book and promote the show for them, especially if they’re already planning a tour in the area. I’ve done that multiple times and it worked out quite well. (Of course, that’s only a good idea if you know what you’re doing.)
