Betty asked me about the upcoming Video Games Live concert, and I realized that I forgot the description! Sorry.
You take an orchestra, and they play the themes from various video games from the earliest to the most recent. Add video clips from the games and add lots of light and bunch of geeky stuff. That is what Video Games Live is about.

Imagine my joy in finding out that the Fort Wayne Philharmonic will be doing this, for one night only at the Embassy! I get my geek fix, and the Prediger gets to go to the Philharmonic.
