The blue (linked) dates indicate shows, the green date is today, and the red date is the day you have selected. All the shows taking place in the selected month are listed at the bottom of the page. Here is the list of artists whose websites I check when updating the calendar.
Someday I'm going to add an Atom and RSS feed to keep you all in the know. My long term goal is to establish an XML format that is devoted to concerts which would be similar in nature to Atom, thus artists could publish their own feeds and I could simply subscribe and filter as necessary. If you are interested in helping with this project in one way or another you should contact me, note that this is not a small undertaking as it requires a DTD, a cross-platform application—or at least a nice web interface—to write the files easily (if it isn't easy, artists won't use it), and a set of plugins to mesh with whatever systems they use now to publish their tour dates.
This calendar does not display shows that have already past.
