The new, free software (iTunes link) from Apple is a universal application designed for both the iPhone and iPad. It requires a device running iOS 4.1 or later, and weighs in at 9.7MB.
"Download the official app now to explore the lineup in more detail and watch the shows LIVE or on demand for a limited period from wherever you are in the world," the official description reads. "You can even invite your friends to watch on the big screen with AirPlay support for streaming the gigs to your Apple TV."
The festival features performances by 62 bands over 31 nights in London, England. Artists include Foo Fighters, Paul Simon, Duran Duran and Moby.
Also performing at this year's festival is Coldplay, a band with a history of ties to Apple. In addition to participating in an Apple commercial, the band's frontman, Chris Martin, performed at Apple's annual iPod event last September, and Apple CEO Steve Jobs was even spotted at a Coldplay concert in 2009.
The broadcasts will be produced by Live Nation, according to All Things D. In addition to Apple's official application, the performances will also be streamed on Live Nation's iOS App Store software.
The iTunes Festival was first held in 2007 at the Institute of Contemporary Arts. This year's event will take place at The Roundhouse in Camden Town, where it has been held in years past.
