Somehow, I didn't notice this thread last time it was around. Celsius and I went from next to no scene in Melbourne, to meeting capacity twice over (we had double as many door sales as capacity for the room) with three internationals in the space of two years.
I've actually been working on a document outlining all the stuff that we have done, both so I have a record, and some day it may be useful to other people
These are my points
a. Your audience is out there, you might just not know it. THEY might not know it. Get as many friends as you can to your shows. Get them to bring their friends. They may show up and then come to every show afterwards.
b. Try different types of advertising. Flyers and posters haven't historically worked for us, so we tend to not do them anymore. But I spam the hell out of the internet. Get involved in forums that have a tenuous link to chip (music forums, video game forums stuff like that). Use facebook and twitter. Local radio is good too, and frequently hard up for something different. We had a chip showcase at an indie games festival. Sure not many people showed up, but they came to SoundBytes afterwards. Try and get the local line music press to come and review your night (have lesbians getting it on in a corner and they'll remember you - trust me!)
c. Charge as little as you can afford to in order get people along at first. Gold coin donation might work, especially if a venue will do you a cut of the bar sales so you can recover some costs
d. Finally, don't over extend yourself. You probably aren't going to pack a 300 venue in the early days. But a little 70 person venue that is packed out, and cheaper for you, and has an amazing vibe from people that want to be there will get people back. Likewise, a monthly show probably won't get people to the same show every month, doing it quarterly will mean that they're excited for the next one.
e. Finally, musicians want to play. You might not have many chip peeps locally, but if you ask nicely and offer them a percentage of your door sales and a place to sleep, and they might just come and play even if they lose money on it but get to hang out and play chip to a crowd
Sorry so long. Believe it or not I had more to say and cut it back
