iConcertCal for the iPhone, previously available for the desktop, is a cool new app for music fans like myself. Like the dekstop edition, the iPhone version of iConcertCall plugs into iTunes to bring you a personalized concert calendar to keep you informed of when your favorite bands are playing in your city. According to the developers: 

If any of the artists in your music library are playing in your area, they will automatically show up in a "My Shows" list. A separate list called "All Shows" will let you browse through any and all concerts in your city.

Each concert listing has:

• links to purchase tickets

• an email option to send a reminder to yourself or to alert your friends about a concert

• a built in map to the venue with directions

• a preview button that will allow you to listen to what each of the bands sound like to help you decide if you want to go

The application goes for $2.99 and is available here at the App Store.
