iConcertCal

Off Topic, but too cool not to share: iConcertCal is currently the featured (free) download at Apple.

After installing & (re-)launching iTunes, you select
View>Visualizer>iConcertCal and then View>Turn on Visualizer.
Put in your City, State (or country for non-US) and a radius in miles from that city, and it will generate an iCal-like calender of concerts by artists that are in your iTunes library in venues within that area!
