The iTunes Festival channel has reappeared on Apple TV, not long before the festival kicks off in London. Apple’s iTunes Festival starts September 1 and runs through the whole month. As has been the case previously, the channel will let users watch live HD streaming video of the performances, as well as on-demand recordings after performances have ended. New acts, including Mary J. Blige, deadmau5, and Ed Sheeran, were recently added to the schedule. Currently, only two days of the festival have acts yet to be announced, as the schedule is mostly set.
