Apple’s iTunes Festival is back again this summer in London. If you can’t make the full 31 nights of shows in person, then you catch all the tunes live on any iOS device for free.

From the app page in the iTunes store:

This July, the iTunes Festival returns to London, England. Featuring 31 consecutive nights of incredible live music in one of the UK’s best venues, this is the hottest ticket in town. The lineup includes Coldplay, Linkin Park, Foo Fighters, Paul Simon, Bruno Mars, Adele, My Chemical Romance, Duran Duran, Lang Lang and Moby — to name just a few of the great shows you can watch live on your iPhone, iPad, or iPod touch.

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. You can even invite your friends to watch on the big screen with AirPlay support for streaming the gigs to your Apple TV (compatible only with second-generation Apple TV; requires iOS 4.3 or later).

The festival officially kicked off on Friday and runs until the end of the month. While I can’t exactly seem myself kicking back on the couch to watch a concert streamed on my iPhone, I would definitely dock my phone in some speakers and rock out to some of the featured bands live, or watch the tunes live on the big screen.

What do you think? Are any of you planning on watching any of the iTunes Festival?
