Apple is again offering a free music festival this year featuring top performing artists. Those in London can attend the Apple Music Festival in person, and the rest of us can stream for free, both live and on-demand. Slated for September 19–28, the festival will feature Pharrell Williams, One Direction, Florence + The Machine, and Disclosure. You'll be able to stream the event via the Music app, as well as via the iTunes software and Apple TV. Plus, you can follow the festival on Beats 1, as well as get a "virtual backstage pass" by following the festival in Apple Music's Connect and in iTunes — bringing you exclusive videos, photos, and behind-the-scenes access to your favorite artists.
