Comment around the web to promote your band blog. Promote individual articles and use tools such as Disqus and Gravatar to brand your identity and increase unique visitors
For instance, you create a group around your band name, import your blog rss feed, your Youtube videos, your Last.fm feed, and your Twitter. Customize your group with useful information, don’t flood rooms with useless, unrelated activity. Let people know more about you, and let them know where they can find you.
