I didn't come to 2010 and 2011 editions of Video Games Live because I live in Guarulhos, who is very very long from HSBC Brasil (where happened the recent editions of VGL). So I suggest that the VGL would come on this city.
Here's the site of Guarulhos City: http://novo.guarulhos.sp.gov.br/
And we have the Guarulhos Young Orchestra (translated to Portuguese: Orquestra Jovem de Guarulhos), who could play the various songs of the show with Tommy Tallarico and his gang.
I hope that one day, Video Games Live come to Guarulhos!
