Hot damn, Google now has concert tour information for your favorite acts. The tour info appears to be geo-located and apparently works whether you are logged into your Google account or not. As I write this, all of these are upcoming touring acts for the Philadelphia, PA area.
So I wonder how tour pages can be optimized for Google. For example, if you search Dave Matthews tour, the tour dates don’t explicitly show.
On the other hand, the links to venues and to buy tickets are buried in another layer of the Dave Matthews Web site. My best guess right now is that if a tour page links out to venue/ticket information, it gets preferential treatment in Google results.
