So, I was looking at Mari Iijima's upcoming concerts and found that, though she lives in Los Angeles, her next scheduled concert is in Japan this August. (No, I don't plan to go to Japan during the summer again for a while.)

And then I got to thinking, it would be really cool if someone had already written an automatic calendar that looks at your location and favorite artists and says when they'll next be playing near you.

It only works with iTunes, but this is a neat solution for now. It looks at who you have in your library. Anyone find anything better?
