Since 2007 Apple has been sponsoring a series a concerts at the Roundhouse in London, England. The event takes place throughout the month of September and the only way to get tickets is to win them. The downside is that you have to actually get to London to attend. If you are not in London over the next month you can still enjoy the great music free on your iDevices. You can access the concerts by downloading the free iOS Festival App; this year they have even added a Festival App to Apple TV. For a listing of the artists performing, starting on September 1, click here.
