On April 13th and 14th, the Video Game Live concert is going to Vancouver. Run by Tommy Tallarico, it is a concert that features all kinds of video game music from Mario to Halo. Along with that, there will be video, lighting and even maybe some audience participation. I have never went so I don't know much about it but what I do know is that tickets are on sale now, and after they visit Vancouver, they are heading across Canada for more shows, so check out their website as it might visit you.
