Concert series Video Games Live will throw its biggest production this April 1st in New Orleans, LA, offering more special fx, screens, special guests, and segments than it's ever included in a single show as PBS tapes the event for a nationwide television special airing July 31st (with a companion DVD, Blu-Ray, and music album).

The game music concert will be joined by the Louisiana Philharmonic Orchestra and feature appearances by composers like Marty O'Donnell (Halo), Russell Brower (Blizzard), Gerard Marino (God of War), Christopher Tin (Civilization IV), and many others. Veteran composers and Video Games Live co-creators Tommy Tallarico and Jack Wall (Myst/Mass Effect) will also attend.

The "father of video games" Ralph Baer will appear on stage to demonstrate his Brown Box system, the world's first home video game console, and will challenge a lucky audience member to a match as the symphony provides the sound effects. He will sign autographs and be available for pictures during the post-show meet and greet, too.

As for festivities before the show begins, attendees can look forward to a costume contest, game demos, prize giveaways, and a Guitar Hero competition. PBS plans to film the costume contest and Guitar Hero competition for the special and its DVD/Blu-Ray release.
