One Direction will be among the headline acts at the Apple Music Festival at London's Roundhouse.

The British boyband - composed of Niall Horan, Liam Payne, Harry Styles and Louis Tomlinson - will be one of the star attractions at the event formerly known as the iTunes Festival, which is set to take place from September 19th until September 28th.

Looking forward to the festival, Niall said: ''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!''

Other acts scheduled to perform at the star-studded festival include Florence + The Machine, Disclosure and Pharrell Williams, who has revealed his excitement at the prospect of performing in London once more.

He said: ''Wow, I'm so grateful to be performing at the Apple Music Festival. The Roundhouse is such a historic music venue ... there's always a special energy in the crowd.''

Previous performers at the eight-year-old old event - which has been renamed the Apple Music Festival to support the launch of the new Apple Music app - have included Adele, Lady GaGa and Justin Timberlake.
