Really like the interface and functionality! Great job. Think you'll eventually branch out to other kinds of ticketed events (theatrical productions, what have you) using the same basic format and algorithms?
Congratulations on launching. Suggestions seem like a good place to start. For revenue, you could partner with venues to offer discounted ticket purchases/admission, promotions, merchandise sales, etc.
Reminds me quite a bit of Timbre - with a curiously similar name as well.<p><a href="http://www.timbreapp.com/" rel="nofollow">http://www.timbreapp.com/</a>
The only way to add bands you care about is individually by hand, or importing facebook likes?!<p>I thought this was going to be an useful, like songkick. I guess not.
