Not to be ousted by The Legend of Zelda: Symphony of the Goddess stopping in Los Angeles during E3, Video Games Live will also be in LA for the the convention. In fact, it'll be the same night at the exact same time as the aforementioned concert. Video Games Live will be at the Nokia Theatre with tickets going from $25 - $75. They also have a limited amount of VIP tickets for $125 that allow you to meet and greet with developers, composers, and producers as well as take a backstage tour, among other things.
It's quite strange they went ahead and announced this show just a week before E3, and also that it will be the same time and date as the Zelda Symphony. I know I myself will be heading over to the Zelda Symphony to see Ms. Williams emcee the show. That's a truly once in a lifetime event! There will be so many more Video Games Live shows for years to come. It's too bad they couldn't space it out, because I would have loved to see both.
