iConcertCal is a free iTunes plug-in that monitors your music library and generates a personalized calendar of upcoming concerts in your city. When iConcertCal first starts up it will try to automatically figure out what city and state you are in by checking your ip adress. But you can easily change your current city and state to search for shows in another town near you, or in a town where you plan to visit.

To change your city and state simply click on the current city and state text boxes and type in your new location. iConcertCal will recognize either your full state name ("California") or the 2-letter abbreviation for your state ("CA"). If you live in Canada, then you can enter your province in the state field.

If you want to see who else is playing at a show you have in your list, simply hove your mouse over the show entry and a full list of all the other acts (that we could find) will be shown in a box above the calendar.
