is a Dashboard widget that scans your iTunes library and offers concert notifications when the artists you actually listen to are coming to a venue near you. The widget uses OnTour.net
to collaborate all this information, and links are provided to buy tickets, as well as to the iTS in case you need to brush up on your choruses. To top things off, the OnTour.net site itself provides even more links to discographies and Google maps for directions. Nice.
