Called iTunes Festival London 2011, this app will turn your iOS device into a source of live music for the whole of next month. So while you may not be able to join the mosh pit or get drenched in the sweat of screaming fans shoving you aside to get to the front of the stage – you’ll be able to watch all the acts on the festival in HD… in the comfort of your own living room. And just in case you miss your favourite artist performing live, you’ll be able to purchase the recordings of the concerts exclusively on iTunes later. Head over to the Apple App Store to download the app now (it’s free).
