Well thats quite handy
Found via Alex King comes the extremely handy iConcertCal for iTunes. This is a quite cool little plugin thingie actually. You download and install it (its free) and it analyzes what songs you play frequently in iTunes and then pulls concert information off the tubes of the internet to give you a nice little calender of when/where your favorite artists are playing in your area, right there in your iTunes. Its already paying dividends, who knew the Roots were coming to Constitution Hall in March? I didn't before but now I do and I'm going to get me some tickets.
Warning: After I downloaded/installed iConcertCal it did shut down my iTunes a couple of times while it was getting concert information but that problem seems to have gone away thankfully.
Holla at me
