Apple has announced the first batch of headliners who will head to London to headline the re-branded Apple Music Festival, former called iTunes Festival. Only four acts have been announced so far, but Apple Music has gone big with their bookings, three from the UK and one from the United States - One Direction, Pharrell, Florence + The Machine and Disclosure.

"Wow, I'm so grateful to be performing at the Apple Music Festival. The Roundhouse is such a historic venue ... there's always a special energy in the crowd. Thank you for having me!" said Pharrell Williams in a statement.

The Cupertino-based company also revealed when each artist will perform. One Direction will headline on Sept. 22, Disclosure conveniently on Sept. 25, the day that their sophomore album Caracal is slated for release, Pharrell the following day on Sept. 26 and then Florence + The Machine will close things out on Sept. 28.

"It'll be great to be back in London and we can't wait to perform for our fans in the Roundhouse and around the world on Apple Music! See you there!" exclaims Niall of One Direction.

Apple Music Festival will occur over 10 days at the historic London venue The Roadhouse from Sept. 19 to Sept. 28. The festival will be broadcasted live and on demand on Apple Music. Additional material will be available through the app's Beats 1 radio station. Backstage news and footage will be streamed right to fans from the artists through Apple Music Connect.

More headliners and supporting acts will be announced soon. If you were considering that three-month free trial, September might be the time to test out Apple Music to catch these sets.
