johnross is right about word of mouth being the secret to building audience, but you have to understand that today, "word-of-mouth" is wired--Text messaging, MySpace, and YouTube are the new media. People connect on MySpace, listen to/watch music clips on YouTube, and keep in touch with each other with Text messaging.

I'd never heard of Rev. Peyton's Big Damn Band, for instance, until Jayto mentioned them above. I've now seen and heard them, courtesy of YouTube, I know bio and schedule stuff, such as when they'll be near me, courtesy of the website, I know a lot about the people who like them, courtesy of their forum and blogs, and I even know that they left Carbondale, Illinois at 10:06 this morning, feeling pretty good about the fact that their new album, "The Whole Fam Damily" debuted at #4 on the Billboard Blues Chart, courtesy of text message, by way of Flicker.

If I wanted to, I could meet other fans, and even get a group of folks together to hear them, or even help to get them bookings, all the same way.

Keep the Flicker thing in mind, because it's probably going to make Email notifications a thing of the past!
