This year's iTunes Festival is really heating up now, as the line-up slowly takes shape.

Joining the likes of Sigur Rós, Vampire Weekend, Justin Timberlake, Queens of the Stone Age and Phoenix will be Arctic Monkeys, Elton John, John Legend and Pixies. Not bad considering you could end up seeing some of these artists for free!

The festival takes place during September at the Roundhouse in Camden. For more information, and to apply for free tickets, head here.
