Apple Releases New Video Featuring iTunes Festival 'Moments'
Artists that performed included Lady Gaga, The Lumineers, Queens of the Stone Age, Kings of Leon, Vampire Weekend, Robin Thicke, Justin Timberlake, Thirty Seconds to Mars, and Jack Johnson.
Though the festival was limited to attendees in the U.K. who won a free ticket via an iTunes lottery system, Apple also provided access through its iTunes Festival app and a dedicated channel on the Apple TV.
The festival will come to a close on September 30 with a performance from Katy Perry. Apple is expected to release a live EP from the show through the iTunes Store after the event ends, as it has done each year.
