Regular contact with the public and, more importantly, your fans through press releases, blogs, articles, Facebook and Twitter is the best way to keep at the top of your fans' minds.
Also be sure to mention how fans can find you online during your live shows. Let them know that they can subscribe to your regular posts and e-mail list to keep up-to-date with you and your musical adventures. This helps fans to feel a part of your unique music culture.
You'll know your efforts are working when you see increased traffic to your websites as well as increased fan participation with blog, Facebook and Twitter comments as well as an increase in subscribers to your e-mail list. All of which will likely result in an increase in audience attendance at your live shows, which will hopefully create an increase in merchandise sales--anyway, you get the picture, it can have a positive and profitable chain reaction effect.
So keep your fans and the public informed about anything and everything you think they might like to know about and publish as often as you can to the internet. This will also help increase your websites' search engine optimization (the more content you produce on the internet the easier it is for search engines like Google to find your sites) making it easier for fans to find you.
