Sixty-one artists are performing at the iTunes Music Festival in London through the rest of July, and Apple is streaming those performances live all month. You can watch the performances either in the iTunes Store via iTunes on your computer, or via the free iTunes Festival London 2011 app, which is designed for iPhone, iPod touch, and iPad. If you watch it on an iOS device, you can use AirPlay to stream it to an Apple TV 2 to see it on the big screen. follow link
